cyclic imines promoted by a chiral zinc complex is reported. In situ generated zinc‐ProPhenol complex with silane afforded pharmaceutically relevant enantioenriched 2‐aryl‐substituted pyrrolidines in high yields and with excellent enantioselectivities (up to 99% ee). The synthetic utility of presented methodology is demonstrated in an efficient synthesis of the corresponding chiral cyclic amines, being pharmaceutical
据报道,由手性锌配合物促进的环状亚胺的首次成功的对映选择性氢化硅烷化。原位生成的锌-苯酚锌与硅烷的络合物以高收率和优异的对映选择性(高达99%ee)提供了药学上对映体富集的对映体富集的2-芳基取代的吡咯烷。所提出方法的合成效用在相应手性环胺的有效合成中得到证明,所述手性环胺是阿替卡普特和拉罗替尼的药物前体。
