Generation of 6H-benzo[f] cyclopenta[d][1,2] thiazepine 5,5-dioxides via a palladium-catalyzed reaction of 2-(2-alkynyl) benzenesulfonamide

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 e...
