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 Rhodium-catalyzed C7-alkylation of indolines with maleimides, published in 2018, which mentions a compound: 4144-22-3, Name is 1-(tert-Butyl)-1H-pyrrole-2,5-dione, Molecular C8H11NO2, Recommanded Product: 1-(tert-Butyl)-1H-pyrrole-2,5-dione.
A rhodium(III)-catalyzed direct cross-coupling reaction of indolines with maleimides via C-H bond activation was developed. This protocol displays good functional group tolerance, which offers a novel approach to access C7 modified indoline derivatives including maleimide analogs I (R = Me, Et, Bn, allyl, etc.; R1 = Me, Et, t-Bu, R2 = R3 = H, Me; -R2R3- = -(CH2)4-; R4 = H, 4-Me, 5-OMe, etc.).
Here is a brief introduction to this compound(4144-22-3)Recommanded Product: 1-(tert-Butyl)-1H-pyrrole-2,5-dione, if you want to know about other compounds related to this compound(4144-22-3), you can read my other articles.
