A novel regioselective rhodium(I)-catalyzed hydroarylation of unactivated alkenes with arylboronic acids is described. The catalytic system employs [Rh(COD)OH]2 and BINAP to effect the addition of various arylboronic acids to protected allylic amines. The regioselectivity was found to be highly dependent on the protecting group, favoring the linear addition product with up to 92% yield and >20:1 regioselectivity
