Organic Electrosynthesis as a New Facile and Green Method for One‐pot Synthesis of Nanosized Particles of Octahydro‐imidazoquinolin‐6‐one Derivatives via a Multicomponent Reaction

Organic electrosynthesis as a new facile and green method was applied for one‐pot synthesis of octahydro‐imidazo[1,2‐a]quinolin‐6‐one derivatives, via a three component condensation of a dimedone, an aldehyde and 2‐(nitromethylene)imidazolidine in propanol in an undivided cell in the presence of sodium bromide as an electrolyte at room temperature. In this study, the anion of dimedone that was produced on the cathode reacted with aromatic aldehydes through the Knoevenagel reaction and then the product condensed with 2‐(nitromethylene)imidazolidine that resulted in a highly efficient formation of octahydro‐imidazo[1,2‐a]quinolin‐6‐one with 50–96% substance yields.
