first been employed as a traceless directing group for the cobalt-catalyzed oxidative annulation of benzylamides with alkynes to synthesize isoquinolines throughC–H/N–H bonds activation. Oxygen is used as a terminal oxidant. This protocol exhibits good functional group tolerance and excellent regioselectivity. Both terminal and internalalkynes can be efficiently applied to this catalytic system as substrates

The oxidative spirocyclization of phenols and naphthols containing pendent amides is described that grants access to unusual spirooxazoline compounds. These rare spirocycles are prepared by an iodine(I)/(III) catalytic cycle.
