available starting materials is described. This enantioselective reaction involves a catalytic asymmetric addition of dialkylzinc reagents to N-diphenylphosphinoylimines with use of an air-stable precatalyst complex 1. The α-chiral amines are prepared with a one-pot procedure from alkyl and aryl aldehydes in good yield (41−90%) and with excellent enantioselectivity (90−97% ee).
描述了通过一锅多组分方法由市售起始原料合成游离α-手性胺。该对映选择性反应涉及使用空气稳定的预催化剂配合物1将二烷基锌试剂催化不对称加成至N-二苯基膦基亚胺。用一锅法由烷基和芳基醛制备α-手性胺,收率好(41-90%),对映选择性极好(ee-90-97%)。
