(54) SPIRO AMINES, THEIR PRODUCTION
AND COMPOSITIONS CONTAINING THEM
(71) We, SUMITOMO CHEMICAL COMPANY LIMITED, a corporation organized under the laws of Japan, of 15, Kitahama-5-chome, Higashi-ku, Osaka, Japan, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is performed, to be particularly described in and by the following statement:
The present invention relates to spiro amine derivatives having antihypertensive activity and central nervous system depressant activity, and to the preparation and use thereof.
More particularly, the present invention provides a spiro amine derivative of the general formula:
Wherein R' is a hydrogen atom, a C1 - C4 alkyl group, a phenyl group which is unsubstituted or substituted by a halogen atom, a Cl - C4 alkyl group or a C1 - C4 alkoxy group, R2 is absent or Rl and R2 together, form a C1 - C4 alkylene radical and thus together with the indolene nucleus define a ring, W is an oxygen atom or two hydrogen atoms and R is a group of the formula:
(wherein A is a C - C4 alkylene, X is absent or is a carbonylgroup, an oxygen atom, the radical )CH-OH or the radical -CG=CH- and R3, R4 and Rt are each optionally present and are each, independently of one another, a Cl - C4 alkyl group, a C1 - C4 alkoxy group, a- benzyloxy group, a halogen atom or a hydroxy group) or
(wherein R6 is a group of the formula:
(wherein R7 is optionally present and is a halogen atom, a cyano group, a C1 - C4 alkyl group, a C1 - C4 alkoxy group or a hydroxyl group),
(wherein R7 is as defined above) or
(wherein R7 is as defined above)), or a pharmaceutically acceptable salt, e.g. an acid addition or quaternary ammonium salt, thereof.
The "halogen" atom may be chlorine, fluorine, bromine or iodine; the C1 - C4 alkyl group may be a straight or branched chain alkyl group having from one to four carbon atoms inclusive (e.g. methyl, ethyl, isopropyl or butyl: the C1 - C4 alkoxy group is an alkoxy group having from one to four carbon atoms inclusive (e.g. methoxy, ethoxy or isopropoxy); the (S - L4 alkylene radical may he metnylene, ethylene, tnmethylene or tetramethylene.
We have found that spiro amine derivatives within the formula (I) as defined above have a hypotensive activity and are useful as anti-hypertensive agents. They also have a central nervous system depressant activity and are useful as transuqillizers and anti-psychotic agents.
Among the spiro amine derivatives of the formula (I) the preferred compounds are those in which W is an oxygen atom. Furthermore, particularly preferred compounds are those within any of the formulae:
wherein Rl, R2 R3 and R7 are each as defined above, and X is a carbonyl group or the radical -CH-OH.
For example, 1'-(3-(4-fluorobenzoyl)propyl)-1-methyl-2-oxo-indoline-3-spiro-4'- piperidine has a potent hypotensive activity at low dosages (0.1 mg/kg - 0.3 mg/kg ip).
In a process within the present invention, a spiro amine derivative of the formula (I) is prepared by reacting a compound of the formula:
wherein Y is absent or is a carbonyl group, a protected carbonyl group, an oxygen atomg the radical =CH-OH or the radical -CH=CH-, Z is a halogen atom and A, R3, R4 and R are as defined above, or a compound of the formula: R6 - B (III) wherein R6 is as defined above and B is a group of the formula:
(wherein Z is as defined above) with a spiro amine derivative of the formula:
wherein Rl, R2 and W are each as defined above, optionally followed by reduction of a carbonyl group, or by hydrolysis of a protected carbonyl group, and optionally salifying the resultant product.
A spiro amine derivative in which R3, R4 or R5 is a hydroxy group can also be prepared by debenzylation of the corresponding benzyloxy derivative.
The condensation reaction is usually carried out in an inert solvent such as an aromatic hydrocarbon (e.g. benzene, toluene, xylene), an amide (e.g. dimethyl-formamide,
N,N-dimethylacetamide), an ether (e.g. dioxane, tetrahydrofuran), an alcohol (e.g.
ethanol, n-butanol, propanol, amyl alcohol), an alkanone (e.g. acetone, butanone, methyl isobutyl ketone) or dimethyl sulfoxide at a temperature within a range of from 0 C to the boiling point of the solvent inclusive. Preferably, a basic substance such as an alkali metal hydrogen carbonate (e.g. sodium hydrogen carbonate, potassium hydrogen carbonate), an akali metal carbonate (e.g. sodium carbonate, potassium carbonate), an alkali metal hydroxide (e.g. sodium hydroxide, potassium hydroxide) or an organic amine (e.g.
pyridine, triethylamine) is used as an acid binding agent. A small amount of a reaction accelerating agent such as potassium iodide may also be added.
The hydrolysis can be carried out by conventional acid. hydrolyzing procedure. For instance, it can be accomplished by treating the protected compound with an acidic substance such as a mineral acid (e.g. hydrochloric acid, sulfuric acid, phosphoric acid), an organic acid (e.g. oxalic acid, tartaric acid) or an acidic ion exchange resin in water or an alkanol (e.g. methanol, ethanol, propanol), usually under mild conditions, e.g. at room temperature. Further, it may be accelerated by elevation of the temperature.
The reduction of a carbonyl group can be carried out in an inert solvent such as an ether (e.g. diethyl ether, tetrahydrofuran, dioxane), an alcohol (e.g. methanol, ethanol, isopropanol), benzene, toluene or water at a temperature within a range of from room temperature to the boiling point of the solvent.
Suitable reducing agents which are preferably employed in the reaction are metal hydride complexes such as lithium aluminium hydride, sodium borohydride, bis-(2-methoxyethoxy) aluminium chloride or sodium aluminium diethyl dihydride, palladium on charcoal or platinum oxide.
A spiro amine derivative of the formula (IV) can be prepared by condensation of an oxoindole derivative of the formula:
wherein Rl and R2 are each as defined above with a dihalide of the formula:
wherein Z is as defined above, optionally followed by reduction of an amide group to give a compound of the formula:
wherein Rl, R2 and W are each as defined above, followed, by debenzylation of the latter.
The condensation reaction of the compound (V) with the compound (VI) can be carried out in an inert solvent such as an aromatic hydrocarbon (e.g. benzene, toluene, xylene) at temperature with a range of from room temperature to the boiling point of the solvent inclusive. A suitable condensation agent is a metal hydride (e.g. sodium hydride, calcium hydride), metal alkoxide (e.g. sodium ethoxide, potassium t-butoxide) or sodium amide.
The debenzylation can be carried out by a conventional catalytic hydrogenation procedure, or by treating the compound (VII) with a compound of the formula:
wherein R8 is a C1 - C4 alkyl group or a benzyl group followed by hydrolysis or hydrogenolysis of the compound of the formula:
wherein R', R2, W and R8 are each as defined above.
