A halogen bond-assisted electron-catalyzed iodination of heteroarenes has been developed for the first time under atom economic condition at room temperature. The iodination is successful with just 0.55 equiv of iodine and 0.50 equiv of peroxide. The kinetic study indicates that the reaction is elusive in the absence of a halogen bond between the substrate and iodine. The formation of a halogen bond, its importance in lowering the activation barrier for this reaction, the presence of radical intermediates in a reaction mixture, and the regioselectivity of the reaction have been demonstrated with several control experiments, spectroscopic analysis, and quantum chemical calculations. Allowing the formation of the halogen bond may offer a new strategy to generate the reactive radical intermediates and to enable the otherwise elusive electron-catalyzed reactions under mild reaction conditions.

Human immunodeficiency virus type 1 (HIV-1) Rev protein facilitates the export of viral RNA from nucleus to cytoplasm, which is a key step in HIV-1 pathogenesis and transmission. In this study, we have screened a commercial library and identified the hit compound 1 bearing a benzenesulfonamide quinoline scaffold that inhibited Rev activity and HIV-1 infectivity. Compounds bearing this scaffold were synthesized and their SAR was studied. We identified compound 20 with low toxicity and potent activity to inhibit HIV-1 replication by affecting Rev function.
