General description: 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.
