Abstract A one‐pot synthetic protocol has been developed using aryl acetic acid as new and alternate surrogate for the synthesis of 4‐aryl imidazoquinoxalines with molecular iodine‐DMSO green catalytic system under classical heating at 100–110 °C. variety quinoxaline derivatives containing quinoline are prepared by this methodology. This a potential to tolerate broad substrates, that is, different amines acids.

Abstract Synthesis of heteroaryl ortho ‐substituted anilines is hitherto challenging. Herein we report scope and limitation method for annulation 1‐(2‐nitroaryl)pyrroles derivatives 2‐aminobenzyl alcohol to afford pyrrolo[1,2‐ a ]quinoxalin‐4‐yl anilines. Reaction conditions contained elemental sulfur as promoter, while were tolerant wide range aryl amines. Our would offer feasible tactic yield steric bulk with heterocyclic substituents.

Abstract We describe herein a method for transition‐metal‐free (hetero)arylsulfonylation of 1‐iodopyrrolo[1,2‐ ]quinoxalines with sodium arylsulfinates. The corresponding aryl iodides were in situ prepared from eletrophilic iodination C1−H bonds pyrrolo[1,2‐ N ‐iodosuccinimide. ensuing sulfonylation only required DMSO as solvent and completed after 15 min. Many arylsulfinates bearing chloro, bromo, methylsufonyl, acetamide, nitro groups competent substrates. Heteroarylsulfonylation also feasible.
