摘要
(Chemical Equation Presented) A catalyst system composed of Pd-(OCOCF 3)2 complexed with the electron-donating, rigid chiral diphosphane Tang-Phos gives excellent enantioselectivities (up to 99% ee) and conversions (up to > 99%) in the hydrogenation of N-tosylimines 1 (see scheme). A variety of aromatic, aliphatic, and cyclic chiral amines 2 can be prepared by this methodology. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
