A new methodology for the synthesis of -substituted -unsaturated -lactones

Author:

Jorge A. Cabezas and Adam Amey

Subject Area:

Life Sciences

Abstract:

A new protocol for the synthesis of -substituted--unsaturated -lactones was developed. Selective reaction of 1,3-dilithiopropyne with ketones, followed by addition of ethyl chloroformate formed ethyl 5-[(ethoxycarbonyl)oxy]-5-substituted-2-ynoates, used as the basic framework for the synthesis of -substituted -unsaturated--lactones.
