Abstract

(1S, 2S, 5R, 6S)-2-Aminobicyclo [3.1. 0] hexane-2, 6-dicarboxylic acid (LY354740) was synthesised enantiospecifically from a sugar derived enantiomerically pure cyclopentenone. The α-amino acid stereogenic centre was formed by reacting the ketone with chloroform anion and then the alcohol so formed was reacted with sodium azide/DBU in methanol to give an azido ester. Critically, this modified Corey-Link reaction gives the opposite ...
