Palladium-complex-promoted asymmetric Diels-Alder reaction: Stereoselective synthesis of a new sulfinyl-substituted phosphine ligand containing three carbon, one phosphorus and one sulfur stereogenic centres

Abstract

Palladium(II) complexes derived from the optically active forms of N,N-dimethyl-1-(1-naphthyl)ethylamine are efficient promoters for the asymmetric Diels-Alder reaction between 1-phenyl-3,4-dimethylphosphole and divinyl sulfoxide; the absolute configurations of the five newly generated chiral centres in this cycloaddition reaction were determined by a crystal structural analysis of a product complex.
