Synthesis of N-Heterocyclic amides from imidazoheterocycles through convergent paired electrolysis
Résumé
An efficient ring opening of imidazoheterocycles induced by a direct C–H azidation resulting in an unusual formation of N-heterocyclic amides has been successfully developed through convergent paired electrolysis. A broad scope of pyridylbenzamides could be obtained in moderate to excellent yields under exogenous-oxidant, electrolyte- and metal-free electrochemical conditions. The methodology was transferred to continuous flow conditions resulting in notable improvements particularly in terms of cost-efficiency over traditional batch versions
