A novel regioselective rhodium(I)-catalyzed hydroarylation of unactivated alkenes with arylboronicacids is described. The catalytic system employs [Rh(COD)OH]2 and BINAP to effect the addition of various arylboronicacids 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

Pd(II)-catalyzed g-G(sp3)-H arylation or heteroarylation of primary amines is realized by using 2-hydroxynicotinaldehyde as a catalytic transient directing group. Importantly, the catalyst and the directing group loading can be lowered to 2% and 4% respectively, thus demonstrating high efficiency of this newly designed transient directing group. Heterocyclic aryl iodides are also compatible with this reaction. Furthermore, swift synthesis of 1,2,3,4-tetrahydronaphthyridine derivatives is accomplished using this reaction.
