Abstract
The modification of sp3-hybridized carbon centers through Pd-catalyzed reductive cleavage of unstrained carbon− carbon σ bonds is described. From the hydrogenolysis of benzyl Meldrum's acids bearing an all-carbon benzylic quaternary center, Meldrum's acid and aromatics substituted with a tertiary benzylic stereocenter were obtained in good to excellent yields. Mechanistic studies showed that the reductive cleavage of enantioenriched ...
