A visible light induced method enables regioselective chalcogenation of indoloquinoxalines.
Efficient chalcogenating agents included thiols, disulfide, and diselenide, improving reaction outcomes.
Developed under metal-free and open-air conditions, the method simplifies the synthetic process.
The approach may expand synthetic versatility in indoloquinoxaline chemistry, using eco-friendly light activation.

Implication

This method demonstrates efficient chalcogenation in indoloquinoxaline derivatives, highlighting metal-free conditions and visible light activation.

Abstract

A simple yet efficient, visible light induced direct, regioselective chalcogenation method of indoloquinoxaline derivatives has been developed. Thiols, disulfide and diselenide were found efficient as chalcogeneting agents in presence of...
