Abstract
P,N-Bidentate oxazoline phosphite containing an acyclic phosphorus center with [(1S)-endo]-(−)-borneol fragments and its palladium chelate complex [Pd(η-C3H5)(η2-P,N)]BF4 were synthesized for the first time. The use of this new ligand in Pd-catalyzed asymmetric amination of 1,3-diphenylpropenyl acetate with pyrrolidine afforded the product with 86% ee.
