Special Issue: Sulfonamides [PDF]
Molecules, 2017 The sulfonamides and their structurally related derivatives, such as the sulfamates and sulfamides, possess the general formula A-SO2NHR, in which the functional group is either directly bound to an aromatic, heterocyclic, aliphatic, or sugar scaffold (of type A), or appended to such a scaffold via a heteroatom, most frequently oxygen or nitrogen ...

NHC-Catalyzed Deamination of Primary Sulfonamides: A Platform for Late-Stage Functionalization.
Journal of the American Chemical Society, 2019 Herein we describe the development and application of a method for the mild, late-stage conversion of primary sulfonamides to several other other functional groups. These reactions occur via initial reductive deamination of sulfonamides to sulfinates via

, 2020 Sulfonamide drugs were the first antimicrobial drugs. The first sulfonamide was trade named Prontosil, which is a prodrug Prontosil, the first commercially available antibacterial with a relatively broad effect The sulphonamides or sulfa drugs competitively inhibit folic acid synthesis in micro-organisms and subsequently inhibit multiplication of ...
