Chalcogen-containing oxazolines in the palladium-catalyzed asymmetric allylic alkylation

Abstract

A comparative study about the ability of chiral chalcogen-containing oxazolines to act as chiral ligands in the palladium-catalyzed allylic alkylation of rac-1,3-diphenyl-2-propenyl acetate with dimethyl malonate is reported. Differences in the catalytic performance are observed with sulfur, selenium and tellurium analogues. © 2006 Sociedade Brasileira de Química.
