A mild and highly efficient copper-catalyzed, one-pot, three-component reaction is developed for the synthesis of homoallyl amines. Reaction of an aldehyde, a carbamate, and allyltrimethylsilane in the presence of 5 mol % Cu(OTf)2 furnishes the corresponding protected homoallylic amines in good to excellent yields.

Tris(pentafluorophenyl)borane, $B(C_6F_5)_3$, was found to be an efficient catalyst for synthesis of N-Cbzhomoallylic amines using Sakurai allylation of N-benzyloxycarbonyl-amino p-tolylsulfones with allyltrimethylsilane.
