The imines ArC(Me)NCH2Ph (Ar = Ph, 2-MeO-C6H4, 3-MeO-C6H4, 4-MeO-C6H4) are hydrogenated to the corresponding amines with extremely high enantioselectivities up to 96% under very mild conditions, using rhodium complexes associated with sulfonated bdpp.
利用与磺化 bdpp 相关联的
铑络合物,在非常温和的条件下将
亚胺 ArC(Me)NCH2Ph(Ar = Ph、2-MeO-
C6H4、3-MeO- 、4-MeO- )氢化为相应的胺,对映体选择性极高,可达 96%。
