Abstract: Here, we report a novel strategy for the direct construction of polycyclic fused ortho-quinone scaffolds through palladium(II)-catalyzed tandem γ-C(sp2)-H arylation and cyclization of arylglyoxals with aryl iodides. This transformation features unique tandem transient directing of… read more here.

Abstract: A photocatalytic tandem radical arylation/cyclization of N-arylacrylamides with diaryliodonium triflates at room temperature affords 3-(benzyl)oxindoles in moderate to good yields. The diaryliodonium triflates upon blue visible light irradiation in the presence of Ir(ppy)2(dtbbpy) · PF6… read more here.
