摘要：

Diastereomeric pure pyridine and 2,2'-bipyridine thioethers, derived from (+)-camphor, were prepared and assessed in the enantioselective palladium-catalyzed allylic substitution of 1,3-diphenylprop-2-enyl acetate with dimethyl malonate. Enantioselectivities of up to 76% were obtained. (C) 1999 Elsevier Science Ltd. All rights reserved.
