On Route to Diverse Nitrogen‐Bridged Polyhetero‐cycles with an N(acyl), N(aryl)‐acetal Core

An expeditious assembling of fused poly-heterocyclic structures having a N(Acyl), N(aryl)-Acetal core has been accomplished by cascade reaction ortho-functionalized anilines with 2-formylbenzonitrile and subsequent intramolecular N-amidic cyclization on different electrophilic carbons. The syntheses have finalized using both cathodically-initiated conventional base-catalyzed methods comparing the two approaches in terms substrate/product scope, efficiency, energy-saving sustainability general.
