into the circulation: (a) a decrease in the blood pressure entering or within the kidney itself; (b) a decrease in the blood volume in the body; or ~c) a fall in the concentra~ion of sodium in the distal tubules of the kidney.
When renin is released into the blood from the kidney, the renin-angiotensin system is activated, leading to vasoconstriction and conservation of sodium, both of which result in increased blood pressure. Renin acts on a circulating p~otein, angiotensinogen! to cleave out a fragment called angiotensin I (AI). AI itself has only slight pharamacologic activity but, after additional cleavage by a second enzyme, angiotensin converting enzyme (ACE), forms the potent molecule angiotensin II (AII). The major pharmacological effects of AII are vasoconstriction and stimulation of the adrenal cortex to release aldosterone, a hormone which causes sodium retention.
Sodium retention causes blood volume to increase, which leads to hypertension. AII is cleaved by an aminopeptidase to form angiotensin III (AIII), which, compared to AII, is a less potent vasoconstrictor but a more potent inducer of aldosterone release.
The renin-angiotensin system has been modulated or manipulated, in the past, with ACE inhibitors. However, ACE acts on several substrates other than angiotensin I
(AI), most notably the kinins which cause such-undesirable side effects as pain, "leaky"-capillaries, prostaglandin release and a variety of behavorial and neurologic effects.
Further, ACE inhibition leads to the accumulation of AI.
Althougn AI has much le55 vasoconstric~or activity than :~ .

~ -3-AII, its presence may negate some of the hypotensive effects of the blockade of AII synthesis.
Inhibition of other targets in the renin-angiotensin sys.em such as AII with compounds such as saralasin can block AII activity, but would leave unimpaired and perhaps enhance the hypertensive effects of AIII.
Inhibitors of renin have been sought as agents for con~rol of hypertension and as diagnostic agents for identification of cases of hypertension due to renin excess.
In efforts to identify compounds which inhlbit renin, compounds have been prepared which mimic angiotensinogen, the natural substrate for renin. In particula_, compounds have been prepared which incorporate mimics of the dipeptide sequence of angiotensinosen preceeding the renin cleavage site ~i.e., mimics of Phe-~is) and which also incorporate non-cleavable mimics of the renin cleavage site of angiotensinogen (i.e., Leu-Val). Compounds comprising mimics of both portions of angiotensinogen bind to renin, but are not cleaved. Thus, renin is inhibited from acting on its natural substr~te.

Sodium retention causes blood volume to increase, which leads to hypertension. AII is cleaved by an aminopeptidase to form angiotensin III (AIII), which, compared to AII, is a less potent vasoconstrictor but a more potent inducer of aldosterone release.
The renin-angiotensin system has been modulated or manipulated, in the past, with ACE inhibitors. However, ACE acts on several substrates other than angiotensin I
(AI), most notably the kinins which cause such-undesirable side effects as pain, "leaky"-capillaries, prostaglandin release and a variety of behavorial and neurologic effects.
Further, ACE inhibition leads to the accumulation of AI.
Althougn AI has much le55 vasoconstric~or activity than :~ .

~ -3-AII, its presence may negate some of the hypotensive effects of the blockade of AII synthesis.
Inhibition of other targets in the renin-angiotensin sys.em such as AII with compounds such as saralasin can block AII activity, but would leave unimpaired and perhaps enhance the hypertensive effects of AIII.
Inhibitors of renin have been sought as agents for con~rol of hypertension and as diagnostic agents for identification of cases of hypertension due to renin excess.
In efforts to identify compounds which inhlbit renin, compounds have been prepared which mimic angiotensinogen, the natural substrate for renin. In particula_, compounds have been prepared which incorporate mimics of the dipeptide sequence of angiotensinosen preceeding the renin cleavage site ~i.e., mimics of Phe-~is) and which also incorporate non-cleavable mimics of the renin cleavage site of angiotensinogen (i.e., Leu-Val). Compounds comprising mimics of both portions of angiotensinogen bind to renin, but are not cleaved. Thus, renin is inhibited from acting on its natural substr~te.

The terms "R" and "S" configuration used herein are as defined by IUPAC 1974 Recommendations for Section E, Fundamental Stereochemistry, Pure Appl. Chem (1976) 45, 13-30.
.The compounds of the invention can be pr~pared as shown in Schemes 1-9. In Scheme 1, the diprotected hydroxyethylene dipeptide isostere 1 ~European Patent Application No. EP364804, published April 25, 1991), or an activated derivative thereof, is coupled to an appropriately functionalized amine 2 (Y and R1 are defined as above) to provide the amide 3. Standard peptide coupling conditions known to those skilled in the art can be used. In particular, the scheme :Lllustrates ~he use of l-hydroxybenzotriazole ~HOBT), 1-(3-dimethylaminopropyl)-
3-ethyl-carbodiimide ~EDCI) and N-mel:hylmorpholine (NMM).
This coupling reaction can be achieved by other standard peptide coupling methods (active ester method, BOP-chloride, as well as other carbodiimides, e.g. DCC, DIC).
The derived amide then can be deprotected by the two-stage method of 1) BOC-removal with trifluoroacetic acid, followed by 2) aqueous hydrolysis of the aminal, whicn produces the aminoalcohol 4. Standard peptide coupling of

The same deprotection/cou?ling sequence described in Scheme 1 then leads to the N-terminal functionalized compound 10. It should be noted that amines such as 7 also may be reacted with sulfur-based electrophiles (sulfenyl, sulfinyl, sulfonyl, or sulfamoyl halides) to produce sulfenamides, sulfinamides, sulfonamides or sulfamides, respectively.
In addition, it should be apparent to those skilled in the art that the method of Scheme 1 can be used to prepare compound 10 wherein in~ermediate 2 i3 appropriately functionalized.
Scheme 3 illustrates an alternate preparation of compound 6. Alkylation of (~)-2-~-omohexanoic acid with the sodium salt of alcohol 11 ~Eu-opean ~atent Application No. EP364804, published April 25, 1991), provides carboxylic acid 5a as a single diastereomer after silica gel column chromatography. ~Alternatively, crude compound 5a can be converted to an active ester derivative (such as the mono- or di-nitrophenylester) ?rior to chromatographic . ., ; .

separation of the diastereomers). The acid 5a (or an active ester derivative) is then coupled to the amino lactone 1~ (Bradbury, R. H.; Revill, J. M.; Rivett, J. E.;
Waterson, D. Te~rahedro.n Lett. 1999, 3~4~) using stand2rd peptide coupling procedures to give the key intermediate 13. Lactone 13 is then reacted with am ne 2 to give the amide 6.
Scheme 4 illustra.es ~he pre?ar2_ion of a representati-~e com~ound of the inventior. having a C-terminal carbo~yl-de-i-ia~ e. ~ ?-o-e^ e~ acid 1 and beta-alanine ethyl ester ~rc cou?led .o give amide 15, which is then deprotec_ed and caz~led ~o ~he desired ac-~5 in a manner analogous to ~hat cescribed i~ Scheme 1.
The derived C-terminal ester 16 is hydrolyzed to the corresponding carboxylic acid 17 by standard methods.
As illustrated in Scheme 5, benzyl carbamates 18 serve as convenient sources of the primary amines 19, by catalytic hydrogenation. The derived amines l9 can be derivati~ed by standard methods. Thus, elaboration with N-acetoxy-norbornene-2,3-dicarboximide gives the N-acetyl compound 20. Treatme~t with trimethylsilyl isocyanate ; gives urea 21. Se~aen.tial r~action with N,N'-thiocarbonyldiimidazole and an a}~ylzmine gives N-substituted thiourea 22. Sulfamide 2~ may be prepared by reaction of 19 with a sulfamoyl chloride.
-Scheme 6 illustrates the preparation of guanidine derivatives and the related 1,2,3-triazoles and 1,3,4-oxadiazoles from amines 19. Amine 19 can be reacted with dimethyl N-cyanoimidodithiocarbonate to give N cyano S-methylisothiourea 24. Compound 24 can be further elaborated by reaction with hydrazine to give 3,5-.

Scheme 7 illustrates another method for preparing the compounds of the invention (6). The protected amino lactone 28 may be converted to amido carbamates 29 by reaction with neat amines at temperatures ranging from 25-75 C. Alternatively, alkylaluminum-mediated lactone openings of ~8 have been desc_ibed to effect this transformation (Ch~kravarty, ~. K.; de Laszlo, S. E.;
Sarnella, C. S.; S~ringer, J. P.; Schuda, P. F.
Tetrahedron Lett. 1989, 30, 415-8). The Boc group can be removed with TFA, and the resulting amine (preferably as the free base) can be coupled to acids 5a, Sb or 5c using standard peptide coupling methodology to provide the compound 6.
Scheme 8 illustrates the preparation of C-terminal derivatives in which the C-terminal ;2mide has been replaced by methyleneoxy, methyleneamino, methylenethio or methylenesulfonyl-derivatives. Boc-lactone 28 i~ reduced with, for example, sodium borohydride-calcium chloride to the diol carbamate 30. The procedures of Karlsson, J. O.;

1989, 30, 2653-6, are adapted for the following transformations. The secondardary alcohol is internally protected by conversion to the oxa~olidinone 31, and the primary hydroxyl group is derivatized. Fox example, the primary hydroxyl group is converted to the methoxymethyl ether 32, or transformed to the sulfide 34 via the ,.. i :, ~' W~92/03429 2 ~ ~ ~ 2 $ 8 PCT/US~1/05s24 ~~3~ ; .
intermediate mesylate 33. The sulfide is oxidized to the corresponding sulfone 35 with a peroxyacid (e.g. m-CPBA or Oxone and the like). Treatment of oxazolines 32, 34, and 35 with barlum hydroxide affords amino alcohols 36, 37, and 38, respectively. Standard peptide co~pling of amino alcohols 36, 37, and 38 with acids 5a or 5b afford products 39.
Scheme 9 illustrates an alternative method for the preparation of compound 5a. ~eaction of aldehyde 40 with an n-butyl organometallic reagent (for example, n-butyl magnesium bromide and the like), followed by o~idative resolution using (-) DT~T t-3uOOH Ti(OCH(CH3)2)4, provides 41 as a sinsle enantiomex. (DIPT is diisopropyl tartrate). Reaction of the alcohol 41 with a halo acetic acid, optionally followed by esterification, or a halo acetic acid ester provides 42 or 43. Alternatively, reaction with t-butyl bromoacetate pr.ovides 44.
Alkylation with a benzyl halide ~for example, benzyl bromide and the like) provides a mixt:ure of 45 and the desired 46. Compound 46 can be separated from the mixture by silica gel chromatography. Hydrogenolysis or hydrolysis of the ester, coupling with 4-methoxymethoxypiperidine and oxidation provides the desired carboxylic acid 5a ~` Scheme 10 illustrates an alternative preparation of intermediate 41. 2-Valeryl furan 47 (prepared by Friedel-Crafts acylation of furan):is stereoselectively reduced ` with diborane and a chiral catalyst (10-20 mole% of a compound such as 48, 49 or 50 and the like (see Scheme 11)) in a solvent such as tetrahydxofuran and the like.

Scheme 2 illustrates a method to prepare compounds of the invention ~herein the C-term nus is furthe-functionali7ed. ~o_ exam?la, th~ am no-'e-~in21 di?rotectad hyG-v~ --nylena v'p-_-'da isostere 7 can be reac~ed wi-h a~?ro?~ia~e elec~rov;.iles 8 to produce amides, ca oamates, ureas or amidines or guanidines, using methods availa~le in the chemical lilerature. The same deprotection/cou?ling sequence described in Scheme 1 then leads to the N-terminal functionalized compound 10. It should be noted that amines such as 7 also may be reacted with sulfur-based electrophiles (sulfenyl, sulfinyl, sulfonyl, or sulfamoyl halides) to produce sulfenamides, sulfinamides, sulfonamides or sulfamides, respectively.
In addition, it should be apparent to those skilled in the art that the method of Scheme 1 can be used to prepare compound 10 wherein in~ermediate 2 i3 appropriately functionalized.
Scheme 3 illustrates an alternate preparation of compound 6. Alkylation of (~)-2-~-omohexanoic acid with the sodium salt of alcohol 11 ~Eu-opean ~atent Application No. EP364804, published April 25, 1991), provides carboxylic acid 5a as a single diastereomer after silica gel column chromatography. ~Alternatively, crude compound 5a can be converted to an active ester derivative (such as the mono- or di-nitrophenylester) ?rior to chromatographic . ., ; .

separation of the diastereomers). The acid 5a (or an active ester derivative) is then coupled to the amino lactone 1~ (Bradbury, R. H.; Revill, J. M.; Rivett, J. E.;
Waterson, D. Te~rahedro.n Lett. 1999, 3~4~) using stand2rd peptide coupling procedures to give the key intermediate 13. Lactone 13 is then reacted with am ne 2 to give the amide 6.
Scheme 4 illustra.es ~he pre?ar2_ion of a representati-~e com~ound of the inventior. having a C-terminal carbo~yl-de-i-ia~ e. ~ ?-o-e^ e~ acid 1 and beta-alanine ethyl ester ~rc cou?led .o give amide 15, which is then deprotec_ed and caz~led ~o ~he desired ac-~5 in a manner analogous to ~hat cescribed i~ Scheme 1.
The derived C-terminal ester 16 is hydrolyzed to the corresponding carboxylic acid 17 by standard methods.
As illustrated in Scheme 5, benzyl carbamates 18 serve as convenient sources of the primary amines 19, by catalytic hydrogenation. The derived amines l9 can be derivati~ed by standard methods. Thus, elaboration with N-acetoxy-norbornene-2,3-dicarboximide gives the N-acetyl compound 20. Treatme~t with trimethylsilyl isocyanate ; gives urea 21. Se~aen.tial r~action with N,N'-thiocarbonyldiimidazole and an a}~ylzmine gives N-substituted thiourea 22. Sulfamide 2~ may be prepared by reaction of 19 with a sulfamoyl chloride.
-Scheme 6 illustrates the preparation of guanidine derivatives and the related 1,2,3-triazoles and 1,3,4-oxadiazoles from amines 19. Amine 19 can be reacted with dimethyl N-cyanoimidodithiocarbonate to give N cyano S-methylisothiourea 24. Compound 24 can be further elaborated by reaction with hydrazine to give 3,5-.

diaminotriazole 25, with hydroxylamine to give 2,5-diamino-oxadiazole 2S, or with ammonia (R1g = H) or an alkylamine (Rlg = alkyl) to give N-unsubstituted or N-substituted guanidine 27.
Scheme 7 illustrates another method for preparing the compounds of the invention (6). The protected amino lactone 28 may be converted to amido carbamates 29 by reaction with neat amines at temperatures ranging from 25-75 C. Alternatively, alkylaluminum-mediated lactone openings of ~8 have been desc_ibed to effect this transformation (Ch~kravarty, ~. K.; de Laszlo, S. E.;
Sarnella, C. S.; S~ringer, J. P.; Schuda, P. F.
Tetrahedron Lett. 1989, 30, 415-8). The Boc group can be removed with TFA, and the resulting amine (preferably as the free base) can be coupled to acids 5a, Sb or 5c using standard peptide coupling methodology to provide the compound 6.
Scheme 8 illustrates the preparation of C-terminal derivatives in which the C-terminal ;2mide has been replaced by methyleneoxy, methyleneamino, methylenethio or methylenesulfonyl-derivatives. Boc-lactone 28 i~ reduced with, for example, sodium borohydride-calcium chloride to the diol carbamate 30. The procedures of Karlsson, J. O.;

1989, 30, 2653-6, are adapted for the following transformations. The secondardary alcohol is internally protected by conversion to the oxa~olidinone 31, and the primary hydroxyl group is derivatized. Fox example, the primary hydroxyl group is converted to the methoxymethyl ether 32, or transformed to the sulfide 34 via the ,.. i :, ~' W~92/03429 2 ~ ~ ~ 2 $ 8 PCT/US~1/05s24 ~~3~ ; .
intermediate mesylate 33. The sulfide is oxidized to the corresponding sulfone 35 with a peroxyacid (e.g. m-CPBA or Oxone and the like). Treatment of oxazolines 32, 34, and 35 with barlum hydroxide affords amino alcohols 36, 37, and 38, respectively. Standard peptide co~pling of amino alcohols 36, 37, and 38 with acids 5a or 5b afford products 39.
Scheme 9 illustrates an alternative method for the preparation of compound 5a. ~eaction of aldehyde 40 with an n-butyl organometallic reagent (for example, n-butyl magnesium bromide and the like), followed by o~idative resolution using (-) DT~T t-3uOOH Ti(OCH(CH3)2)4, provides 41 as a sinsle enantiomex. (DIPT is diisopropyl tartrate). Reaction of the alcohol 41 with a halo acetic acid, optionally followed by esterification, or a halo acetic acid ester provides 42 or 43. Alternatively, reaction with t-butyl bromoacetate pr.ovides 44.
Alkylation with a benzyl halide ~for example, benzyl bromide and the like) provides a mixt:ure of 45 and the desired 46. Compound 46 can be separated from the mixture by silica gel chromatography. Hydrogenolysis or hydrolysis of the ester, coupling with 4-methoxymethoxypiperidine and oxidation provides the desired carboxylic acid 5a ~` Scheme 10 illustrates an alternative preparation of intermediate 41. 2-Valeryl furan 47 (prepared by Friedel-Crafts acylation of furan):is stereoselectively reduced ` with diborane and a chiral catalyst (10-20 mole% of a compound such as 48, 49 or 50 and the like (see Scheme 11)) in a solvent such as tetrahydxofuran and the like.
