Abstract
AbstractA gold(I)‐catalyzed intramolecular dehydrative amination method has been developed to synthesize diverse cyclic sulfamides efficiently. Reactions proceed smoothly at room temperature using a combination of (IPr)AuCl (5 mol%) and AgBF4 (5 mol%). This method showcases a broad substrate scope, encompassing challenging seven‐membered ring structures, and exhibits functional group compatibility. Moreover, the reaction demonstrates high stereoselectivity, allowing the synthesis of enantiomerically enriched cyclic sulfamides from chiral secondary allylic alcohols. The synthesized cyclic sulfamides serve as valuable intermediates for generating 1,3‐diamines. This approach provides an improved route for cyclic sulfamide synthesis and a strategic entry point for obtaining essential 1,3‐diamine derivatives.
