Abstract

A Cp*Ru-based bifunctional catalyst system (Cp* = η5-C5(CH3)5) with a suitably-designed PN ligand (PN = chelating tertiary phosphine-protic amine ligand) has been developed for a regioselective lactonization of unsymmetrically substituted 1,4-diols, which may provide an expeditious access to a variety of lactone lignans.
