Unified Gold-Catalyzed Cyclization Approach Towards Isothiazoles from Propargylic Sulfinamides

CHIMIA
Isothiazoles are valuable heterocycles in agrochemical and pharmaceutical research, yet they remain synthetically less accessible than their isoxazole counterparts. We report here a gold-catalyzed cyclization of propargylic N-tert-butanesulfinamides that
