Abstract

An intramolecular coupling of epoxides with alcohols provides α- and β-substituted γ-butyrolactones depending on the transition metal catalyst used. This methods offers an efficient and practicable way to afford γ-butyrolactones with good efficiency, excellent regioselectivity, and broad substrate scope.
