摘要：

Two types of palladium complexes, cationic (R)-BINAP Pd2+ (SbF6-)(2) and neutral (R)-DABNTf-Pd(CH3CN)(2) were examined as chiral catalysts for enantioselective Claisen rearrangement. DABNTf-Pd(CH3CN)(2) complex gave high enantio- and anti-diastereoselectivity, and good yield. This Claisen rearrangement should proceed via six-membered boat transition state through bi-dentate coordination to the Pd catalyst. (C) 2004 Elsevier Ltd. All rights reserved.
