摘要

Abstract Acetyl derivatives of ethyl esters of 3-(1-naphthyl)-d, l-alanine and 3-(2-naphthyl)-d, l-alanine were synthesized through a malonic condensation. Resolution of these derivatives by subtilisin Carlsberg followed by acid hydrolysis afforded the 2 optical isomers of 3-(1- naphthyl)-alanine [Nal (1)] and 3-(2-naphthyl)-alanine [Nal (2)]. The l enantiomers of these amino acids were incorporated into the sequence of cholecystokinin in place of the ...
