Cu(I)-catalyzed oxidative cyclization of alkynyl oxiranes and oxetanes.

Colombe Gronnier1, Søren Kramer, Yann Odabachian, Fabien Gagosz.   

Abstract

In the presence of a Cu(I) catalyst and a pyridine oxide, alkynyl oxiranes and oxetanes can be converted into functionalized five- or six-membered α,β-unsaturated lactones or dihydrofuranaldehydes. This new oxidative cyclization is proposed to proceed via an unusual allenyloxypyridinium intermediate.
