Abstract

Carbometalation of alkynes is a very attractive reaction for the preparation of stereodefined substituted olefins. 1 Among olefins, R, β-unsaturated ester is one of the most useful compounds in organic synthesis. Metallo-esterification of alkynes is a simple and direct preparative method of such stereodefined substituted metallo-propenoates 1 (eq 1), which can be converted into variously functionalized R, β-unsaturated esters. However, there is ...
