Ruthenium pincer-catalyzed synthesis of substituted γ-butyrolactones using hydrogen autotransfer methodology†
Abstract
The ruthenium pincer-catalyzed synthesis of γ-butyrolactones from 1,2-diols and malonates using borrowing-hydrogen methodology is reported. This regioselective domino-process takes place through catalytic C–C bond formation, followed by intramolecular transesterification. Herein, we show the Ru–MACHO–BH complex as a valuable catalyst in hydrogen autotransfer reactions.
