Article abstract of DOI:10.1016/S0040-4020(01)80065-X

Substitued 2-methylene-tetrahydrofurans are obtained by an efficient cyclisation of acetylenic alcohols and phenols.The presence of an electron-withdrawing group activates the triple bond and leads to high yields under weakly basic or acidic conditions.Ou
