摘要

Abstract An asymmetric synthesis of the six-carbon α-amino acids (ϵ-13 C)-L-α-aminoadipic acid and various isotopomers of L-lysine is described. The synthesis is based on a general method starting from the bis-lactim ether of cyclo (D-Val-Gly) and simple labelled reagents like K 13 CN, K 13 C 15 N, 13 CH 3 CN and LiAl 2 H 4. Using this route (ϵ-13 C)-L-α- aminoadipic acid was prepared in 31% yield based on the labelled potassium cyanide. ...
