The reaction of enantiopure imine 1 with methallyl or prenylzinc reagents affords homoallylic amines having (S,S) configuration with up to 100% diastereomeric excess. Another diastereomer, (R,S)-amines, is obtained from the same imine 1 by using allylboron reagents.
手性纯烯胺1与甲基丙烯基或普伦基锌试剂的反应生成具有(S,S)构型的同伴胺,反应的二级立体化合物过量可达100%。另一种二级立体异构体(R,S)-胺则是通过使用烯基硼试剂从同一烯胺1获得的。
