CPC classification number: C07D453/04

Abstract: OPTICAL ANTIPODES D- AND L-N-BENZOYL-3,4-DIHYDROXYPHENYLALANINE OF THE FORMULA:

1-(PHENYL-CO-NH-CH(-COOH)-CH2-),3,4-DI(HO-)BENZENE

AND THE CINCHONNE SALTS THEREOF. THESE COMPOUNDS ARE MADE BY REACTING CHINCHONINE WITH D- AND OR L-N-BENZOYL-3,4-DIHYDROXYPHENYLALANINE AND THEN CRYSTALLIZING THE SALT FROM MIXTURES OF WATER WITH LOWER KETONES,LOWER ALKANOLS LOWER ETHERS OR MIXTAURES THEREOF IN ORDER TO SEPARATE AND RESOLVE THE OPTICAL ISOMERS. THESE SALTS ARE CLEAVED TO THE OPTICALLY PURE- OR L-N-BENZOYL-3,4-DIHYDROXYPHENYLALANINE WHICH IS ITSELF CLEAVED TO 3,4-DIHYDROXYPHENYLALANIME.
