A novel and expedient one-pot synthesis of thiazino[2,3,4-hi]indole derivatives was developed through a tandem oxidative coupling/heteroannulation process.
The one-pot reaction includes sequential intermolecular addition of thioamides to nitriles, and intramolecular oxidative coupling of N–H and S–H bonds mediated by molecular iodine.
