CONVENIENT SYNTHESES AND REACTIONS OF TWO KINDS OF BASIC α-DEHYDROAMINO ACID DERIVATIVES

Shin, Chung-gi,Obara, Takumi,Segami, Shigenori,Yonezawa, Yasuchika

, p. 3827 - 3830 (1987)

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.
