摘要:
Rh(III)-catalyzed C -H bond annulation of 2-arylquinoxalines with cyclic 2-diazo-1,3-diketones has been accomplished for the first time to synthesize a novel series of 2,3dihydrodibenzo[a,c]phenazin-4(1H)-one frameworks by means of carbene insertion followed by condensation. The reaction proceeds through the C -H bond activation and functionalization of 2-arylquinoxalines using Rh(III)/AgSbF6 complex to produce highly substituted 2,3-dihydrodibenzo[a,c]phenazin4(1H)-one and benzo[5,6][1,2,4]thiadiazino[2,3-f]phenanthridin5(6H)-one-10,10-dioxide derivatives in good to excellent yields.
