cis- And trans-2,2-dimethyl-4-carbomethoxy-5-phenylthiazolidines prepared from the corresponding erythro- and threo-β-phenylcysteines were resolved into the enantiomers by use of a chiral HPLC column, from which all of the four chiral β-phenylcysteine met
THE SYNTHESES OF N-FREE α-DEHYDROAMINO ACID ESTERS AND N-ACETYL DEHYDRODIPEPTIDE ESTER FROM N-CARBOXY α-DEHYDROAMINO ACID ANHYDRIDE

N-Carboxy α-dehydroamino acid anhydride, derived from N-benzyloxycarbonyl α-dehydroamino acid (DHA) and thionyl chloride, was found to be very useful for the synthesis of N-free DHA ester by alcoholysis and N-acetyl dehydrodipeptide ester by coupling was
The Preparation and Reactions of 2-Benzyloxy-4-benzylideneoxazol-5-one
Jones, John H.,Witty, Michael J.
