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. 1 H 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.
