Abstract

It is shown that acid hydrolysis of dibenzoyl-D-cystathionine or-1anthionine is accompanied by partial racemisation. An unsuccessful attempt has been made to show that the enzymic synthesis of dibenzoylcystathionine dianilide is stereospecific for the L-isomer. Acid- hydrolysis of this dianilide and the similarly prepared dibenzoyl-L-lanthionine dianilide gives partially racemic products.
