Palladium-catalyzed enantioselective C-H arylation for the synthesis of P-stereogenic compounds

Abstract

A palladium-catalyzed enantioselective C-H arylation of N-(o-bromoaryl)-diarylphosphinic amides is described for the synthesis of phosphorus compounds bearing a P-stereogenic center. The method provides good enantioselectivities and high yields. The products were readily transformed into P-chiral biphenyl monophosphine ligands.
