Descripción
Sumario:[Image: see text] Efficient access to 8H-isoquinolino[1,2-b]quinazolin-8-ones and phthalazino[2,3-a]cinnoline-8,13-diones through cyclic amide-directed Ru(II)/Ir(III)-catalyzed C–H bond activation, has been developed. Consecutive C–H bond activation, carbene insertion, and condensation annulation processes were realized, affording 8H-isoquinolino[1,2-b]quinazolin-8-one and phthalazino[2,3-a]cinnoline-8,13-dione derivatives in good-to-excellent yields under mild conditions, with H(2)O and N(2) being generated as the only byproducts.
