The allylation of stable, protected imine precursors, α-amido sulfones, with allylic acetates to form homoallylic amines is catalyzed by nickel under mild reducing conditions. Aliphatic and aryl imines are tolerated, as are substituted allylic acetates. I

An efficient method for the one-pot synthesis of secondary and tertiary N-homoallylic carbamates using catalytic amount of HBF4·OEt2is described. The reaction proceeded smoothly to afford the corresponding N-homoallylic carbamates in good to high yields. Operationally simple and easily scalable features make this method more practical over existing methods. Use of HBF4·OEt2as an acid catalyst also proves the catalytic activity of fluorinated acid catalyst in this important organic transformation.
