Convenient synthesis and conversion of a (Z)-α,β-didehydroornithine derivative to α,β-didehydrokyotorphin

Yonezawa, Yasuchika,Hirosaki, Takako,Hayashi, Takashi,Shin, Chung-Gi

, p. 144 - 148 (2007/10/03)

Hydrogenolysis of the azido group of methyl (Z)-2-(N-Cbz)amino-5- azidopent-2-enoate, derived by selective reduction and azidation of the side chain carboxyl group of N-protected (Z)ΔGlu-OMe, gave (Z)-α,β- didehydroornithine derivative (7). The formed 7 was further converted to the basic (Z)-α,β-didehydroarginine and the acid containing (Z)-α,β- didehydrokyotorphin.
