sulfamoylation

Sulfamoylation is a chemical reaction that involves the introduction of a sulfamoyl group (-SO2NH2) into a molecule. This is typically achieved by reacting a compound with a sulfamoylating agent. Common sulfamoylating agents include sulfamoyl chloride (ClSO2NH2) or chlorosulfonyl isocyanate (ClSO2NCO). The reaction can occur with various nucleophiles, such as amines, alcohols, or even carbon atoms under specific conditions.

The sulfamoyl group is an important functional group in medicinal chemistry and organic synthesis. Many pharmaceuticals contain sulfamoyl moieties, contributing to their biological activity. For instance, some diuretics and carbonic anhydrase inhibitors feature this group. In organic synthesis, sulfamoylation can be used to modify the properties of molecules, alter their reactivity, or introduce new functionalities for further transformations. The conditions for sulfamoylation vary depending on the specific substrate and reagent used, often requiring a base to facilitate the reaction and scavenge any acidic byproducts. The precise mechanism can involve nucleophilic attack on the sulfur atom of the sulfamoylating agent.
