Heteroaryl 2‐Sulfonamide Synthesis by SN2 Reaction–Oxidation Cascade

Abstract

AbstractHeteroaryl 2‐sulfonamides are an important structural moiety in drug discovery. However, reports of the efficient synthesis of these scaffolds are rare. Herein we disclose new reaction conditions to synthesize heteroaryl 2‐sulfonamides from disulfanes and amines through an SN2‐oxidation cascade. The approach is compatible with a wide variety of heteroaryl and amine substrates and can be conducted on a gram scale. A potential Werner Syndrome Protein (WRN) small molecule inhibitor H3B‐968 was also synthesized by this method.
