Two kinds of basic N-carboxy α-dehydroamino acid anhydrides (ΔNCA) were synthesized by the cyclization of N-benzyloxycarbonyl (Cbz)-α-dehydro-ornithine and -lysine (DHA), derived from Cbz-aminoaldehydes and N-Cbz-2-(diethoxyphosphinyl)glycine esters.Moreover, facile conversion of Cbz as Nα-protecting group in DHA to Boc via ΔNCA was also successful.
