Rh(I)-new chiral diphosphinite systems with terminal amino groups were very effective for asymmetric hydrogenation of dehydrodipeptides with free carboxyl group and a chiral carbon. The effectiveness of the diphosphinite catalysts strongly suggests the contribution of electrostatic effect to asymmetric induction.
Rh(I)-具有末端氨基的新型手性二次膦酸盐体系对于具有游离羧基和手性碳的脱氢二肽的不对称氢化非常有效。二亚膦酸盐催化剂的有效性强烈表明静电效应对不对称感应的贡献。
