Descripción

General description

Chlorosulfonyl isocyanate is classified as an isocyanate and is widely used as a reagent in sulfonylation and carbamoylation reactions.Chlorosulfonyl isocyanate reacts with hydrocarbon alkenes via stepwise dipolar pathway to give N-chlorosulfonyl-β-lactams.

Application

• Chlorosulfonyl isocyanate was used in synthesis and biochemical characterization of new class of membrane-associated glycosyltransferase inhibitors.
• It is synthetically versatile reagent and was used in the preparation of amides, lactams and triazocinones.
• It was employed in regio- and diastereoselective introduction of a protected amino group in synthesis of chiral, polyhydroxylated piperidines.
• It was used as reagent during the synthesis of novel sulfamides.

Employed in a regio- and diastereoselective introduction of a protected amino group in a synthesis of chiral, polyhydroxylated piperidines. Generation of ureas from amino groups in a synthesis of benzimidazolones.
