Stereospecific and efficient alkynylation at the more hindered carbon of trisubstituted epoxides.

Hongda Zhao1, Brian L Pagenkopf.   

Abstract

The stereospecific and regioselective C(3) alkynylation of trisubstituted epoxides has been achieved with lithium alkynyl trimethylaluminium ate complexes in the presence of BF3 x OEt2.
