An efficient approach for the assembly of 6H-benzo[f]cyclopenta[d][1,2]thiazepine 5,5-dioxides via a palladium-catalyzed tandem reaction of 2-(2-alkynyl)benzenesulfonamide with 2-alkynylvinyl bromide is reported. This transformation proceeds smoothly through a double carbopalladation with high efficiency.

The incorporation of the (trifluoromethyl)thio group into the benzo[e][1,2]thiazine 1,1-dioxide scaffold via a reaction of trifluoromethanesulfanylamide with 2-(2-alkynyl)benzenesulfonamide is reported. The transformation proceeds under mild conditions to afford the 4-((trifluoromethyl)thio)-2H-benzo[e][1,2]thiazine 1,1-dioxides in moderate to good yields.
