Microwave-accelerated asymmetric allylations using cysteine derived oxazolidine and thiazolidine palladium complexes

Braga AL, Silveira CC, de Bolster MWG, Schrekker HS, Wessjohann LA, Schneider PH

A set of enantiopure oxazolidine-thioether and thiazolidine-alcohol palladium complexes catalyze the microwave-mediated enantioselective allylation of rac-1,3-diphenyl-2-propenyl acetate with dimethyl malonate. Good yields and ee's were achieved in reaction times of 2 min instead of hours with conventional heating. (c) 2005 Elsevier B.V. All rights reserved.
