Metal‐Free Synthesis of 2‐Aminobenzothiazoles via I2‐Catalyzed Tandem Cyclization Reaction of Amines and Carbon Disulfide

Comprehensive Summary A convenient approach for the construction of 2‐aminobenzothiazoles via I 2 ‐catalyzed tandem cyclization reaction of amines and carbon disulfide has been developed. The present approach starts from simple and readily available starting materials, affording a series of 2‐aminobenzothiazoles in up to 89% yields under metal‐free conditions. In this work, C—H/N—H functionalization was achieved and multiple C‐hetero bonds were successfully constructed in one pot.
