摘要：

[GRAPHICS] A chiral rhodium complex, (R)-Cp*RhCl[(1S,2S)-p-TsNCH(C6H5)CH(C6H5)NH2] (1a, (S,S)-Cp*RhCITsDPEN), generated from [Cp*RhCl2](2) and (1S,2S) N-p-toluenesulfonyl-1,2-diphenylethylenediamine [(S,S) TsDPEN], and its enantiomer 1b were found to provide superior catalysts for the rapid, high yielding, asymmetric transfer hydrogenation of some heterocyclic imines, using an HCO2H-Et3N azeotrope as the hydrogen source.
