Abstract

A practical and efficient synthesis of triazolothiadiazepine-1,1-dioxide derivatives via copper-catalyzed [3+2]cycloaddition, followed by N-arylation is described. The method is also applicable to the synthesis of indoline- and thiophene-fused triazolothiadiazepine 1,1-dioxide derivatives.
