A facile one-pot synthesis of dicycloalkenopyridines at ambient temperature conditions

An efficient synthesis of dicycloalkenopyridines was achieved via one-pot three-component condensation of aromatic aldehyde, cyclohexanone, and hydroxylamine hydrochloride using 3-nitrophenylboronic acid as an efficient catalyst under ambient condition. The current methodology offers several advantages such as high yields (78-90%) and simple experimental work-up at ambient temperature conditions.
