α-Oxo gold carbenoids generated by the oxidation of N-arylynamides can be trapped intramolecularly at the ortho position of the aryl ring to give functionalized oxindoles under mild reaction conditions. PyridineN-oxide works as the oxidant, ligand, and base in this transformation.

A one-pot cascade reaction for the synthesis of 2-BMIDA 6,5-bicyclic heterocycles has been developed using Cu(I)/Pd(0)/Cu(II) catalysis. 2-Iodoanilines and phenols undergo a Cu(I)/Pd(0)-catalyzed Sonogashira reaction with ethynyl BMIDA followed by...
