Resumo

A simple and direct palladium-catalyzed aminocarbonylation of 5-iodo-1,2,3-triazoles backbone for the incorporation of an amide functional group is presented. The approach is based on the palladium catalyzed carbonylative coupling reaction of iodo-triazole with different amines employing formic acid and sulfuric acid as CO source (Morgan's reaction) to provide the 1,2,3-triazole-5-carboxamides in good to excellent yields. The important features of this methodology include short reaction time, high yields, the use of dimethyl carbonate as a sustainable solvent, and the use of efficient alternative source of carbon monoxide, avoiding pressurized cylinder. The methodology described herein for the synthesis of 1,4,5-trisubstituted 1,2,3-triazole-5-carboxamides, can offers an alternative path for functionalization of other heterocycles. (AU)
