Summary of main observation and conclusion Herein, we report a practical protocol for the synthesis of sulfur cycle fused 1,2,3‐triazoles through a copper(I)‐catalyzed tandem click/intramolecular sulfenylation reaction. The reaction proceeded via a copper‐catalyzed alkyne azide cycloaddition, followed by interception of the in situ formed cuprate‐triazole intermediate with p ‐toluenesulfonothioate. This reaction shows broad substrate scope, complete regioselectivity, and excellent functional group tolerance under mild reaction conditions.
