| 摘要 |
The present invention relates to a process for the synthesis of optically pure D- alpha -amino acid amides, characterised in that there is used as starting materials a mixture of D- and L-amides of amino acids in which the amine functional groups have been protected and in that this mixture is subjected, in an aqueous medium, to a hydrolysis at a pH of about 7 to about 9, at a temperature of 10 to 60 DEG C in the presence of papain.
