The synthesis of (iso)quinoline-indole hybrids by reacting (iso)quinoline N-oxides with o-alkynylanilines in the presence a combination copper(II) catalyst and bidentate 2,2′-bipyridine ligand is described. utility this method was demonstrated through site-selective functionalization synthesized products. A plausible reaction pathway for amination followed annulative indole formation elucidated series mechanistic investigations.

A Ru(II) catalyzed regioselective Heck-type C-H olefination of isoxazole with unactivated allyl phenyl sulfone is revealed. The solvent DCM offers dual sp2-sp2 activation via an N-directed strategy, leading to ortho-olefinated isoxazoles exclusive E-selectivity. On the other hand, in DCE solvent, serves as nitrile synthon and leads o-olefinated benzonitrile. At a higher temperature (110 °C) DCE, after ortho-olefination mediated cleavage delivered functionality.
