Application

2-Chloroethanesulfonyl chloride was used in one-pot sulfonylation/intramolecular thia-Michael protocol for the synthesis of 1,5,2-dithiazepine 1,1-dioxides. It was also used in synthesis of vinylsulfonamides with a furan, carbocyclic, semicyclic or acyclic 1,3-diene moiety.

Vinylsulfonamides with a furan, carbocyclic, semicyclic or acyclic 1,3-diene moiety are synthetized via a domino elimination-amidation reaction of 2-chloroethanesulfonyl chloride. Intramolecular Diels-Alder reaction of these vinylsulfonamides with thermal (toluene, 110 degrees C) or high pressure (dichloromethane, 13 kbar) activation provides
