In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Electrochemical diselenylation of indolizines via intermolecular C-Se formation with 2-methylpyridines, α-bromoketones and diselenides, published in 2020, which mentions a compound: 65438-97-3, Name is 2-Bromo-1-(1-methyl-1H-pyrrol-2-yl)ethanone, Molecular C7H8BrNO, Formula: C7H8BrNO.
2-Methylpyridines, aryl bromomethyl ketones, and diselenides underwent electrochem. three-component cyclocondensation and selenylation reactions mediated by KI and K2CO3 in aqueous DMF to yield diselenylindolizines such as I [R = Ph, 4-R1C6H4, 3-R2C6H4, 2-FC6H4, 2,4-Cl2C6H3, 3,4-Cl2C6H3, 3,4-(MeO)2C6H3, 2-naphthyl, 1,3-benzodioxol-5-yl, 2-dibenzofuranyl, 1-methyl-2-pyrrolyl; R1 = Me, MeO, i-Bu, F, Cl, Br, I, F3C, Ph, PhCH2O, MeSO2; R2 = Me, MeO, Cl, Br].
