A novel and efficient method for the regioselective bromination of pyrrolo[1,2-a]quinoxaline using tetrabutylammonium tribromide was developed. A series of highly selective C3-brominated or C1, C3-dibrominated products were obtained in good yields.
The synthesis of pyrrole-fused heterocycles is demonstrated using the first biomass-derived glucose-mediated one-pot multicomponent nitro reductive cyclization method.
In this review, we have summarized the recent progress in two-component and three-component synthetic approaches for the eco-friendly construction of functionalised and fused quinoxaline frameworks.
An atom-economic, functional-group–tolerant photocatalytic sulfenylation and selenylation of a variety of indoloquinoxalines under aerobic conditions, at rt.
We report a mild and efficient copper-catalyzed method for synthesizing amino-substituted pyrrolo[1,2-a]quinoxaline and indolo[1,2-a]quinoxaline derivatives via the insertion of o-benzoylhydroxylamines into aryl isocyanides.
