(Phenyl)(3-phenylsulfonyl-1,2-dihydropyrrolo[1,2-a]quinoxalin-1-yl)methanone
In the title molecule, C24H18N2O3S, the 13-atom ring system comprising the quinoxaline and fused five-membered ring exhibits an r.m.s. deviation from coplanarity of 0.039 Å, with a maximum deviation of 0.0710 (10) Å for the PhCO-bearing C atom of the five-membered ring. The 10-membered C8N2 quinoxa...
