A one-pot procedure for the preparation of highly functionalized 3-methylenetetrahydrofurans is described. The methodology is based on an oxygen nucleophile initiated Michael addition of propargyl alcohols to alkylidene or arylidenemalonates followed in situ by a palladium-mediated exo-dig cyclization.
