摘要：
The catalytic enantioselective addition of allyltributylstarmane to N-protected ot-iminoesters promoted by silver(l) trifluoromethanesulfonate in the presence of chiral imine ligands was studied. After testing several chiral imines derived from 1,2-diaminocyclohexane and binaphthyl diamine a very simple experimental proc-edure was developed that allowed us to obtain optically active homoallylic amines in very high yields and enantioselectivities up to 71%.
