Abstract

The annulation of a methylenecyclopropane with acyl cyanoalkenes by using DABCO or quinuclidine as a catalyst to give 2,3‐dihydofurans has been developed. A stoichiometric amount of the Lewis bases promoted the isomerization of 2,3‐dihydrofurans to furans. 1H NMR spectra of the reaction in situ revealed that the methylenecyclopropane is opened by the Lewis base to form a reaction intermediate that is added to the cyanoalkenes.
