The synthesis of N-carboxy α-dehydroamino acid anhydrides (ΔNCA) from benzyloxycarbonyl-α-dehydroamino acids and the subsequent conversion of these products into new α-dehydroamino acid and dehydrooligopeptide derivatives are described. It was found that the new ΔNCA derivatives were very useful synthons for dehydropeptides. The racemization behavior and configurational determination of all the new dehydrooligopeptides thus obtained are discussed.
