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.
