Optical Resolution of Racemic S-(Carboxymethyl)cysteine

Racemic S-(carboxymethyl)cysteine obtained from racemic cysteine is resolved via its ammonium salt (R,S)-3 by preferential crystallization procedure.Furthermore, (R,S)-2 forms with optically active amines separable, diastereomeric salts.Thus, (1R,2S)-2-amino-1-phenyl-1-propanol (4) affords optically pure (R)-S-(carboxymethyl)cysteine in 93 percent yield.The resolution of (R,S)-2 is also possible with (R)-1-phenylethylamine (5).
