Zinc-catalyzed Meinwald rearrangement of tetrasubstituted 1-alkynyloxiranes to tertiary α-alkynylketones

Abstract

Easy access to tertiary α-alkynylketones via a Meinwald-type rearrangement of 1-alkynyloxiranes is reported. This transformation is selectively accomplished with an economical zinc catalyst.
