ABSTRACT:
Optically active mono-esters of dicarboxylic acid of the formula III: ##STR1## being useful as intermediates for preparing optically active natural products or medicines; asymmetric synthesis process for preparing thereof being characterized by the reaction of an acid anhydride with an (R)- or (S)-arylacetic acid derivative; and the key substances therefor are also claimed.
