Abstract
A process for the preparation of L-α-hydrazino-P-phenylpropionic acid compounds of the general formula **(See formula)** where R1 and R2 represent hydrogen or hydroxy or alkoxy groups containing at most 6 carbon, phenyloxy or benzyloxy atoms; R3 and R4 are hydrogen or alkyl groups having at most 6 carbon atoms and is hydrogen, a metal atom or an alkyl group having at most 6 carbon atoms, characterized by oxidizing the L-isomer of a compound of formula: **(See formula)** where R3, R4 and R5 have the meaning given above R6 is hydrogen or an acyl group containing a maximum of 30 carbon atoms and R7 is NH2 or N = R8 is a divalent radical, to form the corresponding 3,4-dihydroxy derivative.
