  General and practical catalytic enantioselective Strecker reaction of ketoimines: significant improvement through catalyst tuning by protic additives

  摘要：

  Significant improvement in enantioselectivity and catalyst activity was achieved for the catalytic enantio selective Strecker reaction. Using a catalyst (1-2.5 mol%) prepared from Gd((OPr)-Pr-i)(3) and D-glucose derived ligand 1, and in the presence of 2,6-dimethylphenol as an additive, high enantioselectivity was obtained from a wide range of ketoimines, including heteroaromatic and cyclic ketoimines. The new method was applied to an efficient catalytic asymmetric synthesis of sorbinil, a therapeutic agent for diabetic complications. (C) 2004 Elsevier Ltd. All rights reserved.

  Catalyst loading as low as 0.1 mol % was achieved in the enantioselective Strecker reaction of ketoimines. Excellent enantioselectivity was obtained with a combined use of a catalytic amount of TMSCN and a stoichiometric amount of HCN as a reagent, and a chiral gadolinium complex as a catalyst.

  在酮亚胺的对映选择性斯特雷克反应中，催化剂的负载量低至0.1摩尔％。结合使用催化量的TMSCN和化学计算量的HCN作为试剂，以及手性g络合物作为催化剂，可获得出色的对映选择性。
