Divergent Synthesis of 4‐Aminotriazoles Through Click Cycloaddition and Generation of Iodonium(III) Triazoles

Le résumé fourni par la source

Abstract The divergent synthesis of 4‐amino‐1,2,3‐triazoles was accomplished through the Cu‐catalyzed cycloaddition of organic azides with alkynyliodonium(III) salts, followed by Cu‐catalyzed triazole‐amine coupling involving treatment with amines and amides. The in situ formation of 1,2,3‐triazole iodonium salts is crucial to this approach, and the utilization of a Cu‐catalyst facilitates cycloaddition and C−N bond formation. The synthesis of 1,2,3‐triazolyliodonium(III) salts proposed in this study offers advantages, including mild reaction conditions, a broad substrate scope, and operational simplicity, while also providing efficient access to a complex and diverse range of 4‐amino‐1,2,3‐triazole derivatives.
