Abstract

Procedure for the preparation of amino acids of the general formula **(See formula)** wherein R1 represents hydrogen, hydroxyl, lower alkyl, lower alkoxy, nitro or amino halogen, n denotes an integer valued from 1 to 3; R2 represents hydrogen or lower alkyl; R3 represents hydroxyl or (optionally mono- or di-substituted by lower alkyl), amino; R4 represents hydrogen, lower alkyl, lower alkanoyl, or aroyl; and R5 represents hydrogen or lower alkyl, preferably in the form of L or D, L, and of salts of these compounds, characterized in that a compound of the general formula undergoes an oxidative rearrangement **(See formula)** where R1, R2, R3, R4, R5 and n have the same meaning as before, while one of the substituents R6 and R7 represents hydroxyl and the other represents lower alkanoyl, aroyl or carboxyl, preferably in the form of L or D, L, or a salt of such a compound, and the carboxylic acid ester obtained is saponified and, in the order of succession desired, the compound of formula I is hydrolyzed, if desired. obtained, resolved into optically active forms, if desired, a racemate obtained and converted, if desired, into a salt.
