| Abstract: | Two types of palladium complexes, cationic  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. |
