Abstract
Procedure for the preparation of amino acids of the general formula **(See formula)** wherein R1 represents hydrogen, hydroxy, lower alkoxy, lower alkyl, halogen, or amino; n is an integer valued from 1 to 3; R2 represents hydrogen or lower alkyl; R3 represents hydroxy, lower alkoxy or amino mono- or di- (lower alkyl) -substituted, R4 represents hydrogen, lower alkyl, lower alkanoyl or aroyl; R5 represents hydrogen or lower alkyl, and one of the symbols R6 and R7 represent hydroxyl while the other represents lower alkanoyl, preferably in L or D, L form, and of salts of these compounds, characterized by reacting a compound of the general formula **(See formula)** wherein one of the symbols R'6 and R'7 represents hydrogen while the other represents hydroxyl, preferably in the form of L or D, L, or a salt of such a compound, with a functional derivative of a lower alkanocarboxylic acid, in the presence of a FriedelCrafts reagent, and in any order of succession, hydrolyze the product obtained from the Reaction, if desired, optionally settle in the optically active forms a racemate obtained, and, if desired, convert a base obtained into a salt.
