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. (C) 2012 Elsevier Ltd. All rights reserved.

microwave irradiation, the one-pot multicomponent condensationreaction of three molar aromatic aldehydes with two molar cyclicketones having free α,α′-methylene positions such as cyclopentanone or cyclohexanone in the presence of ammonium acetate and acetic acid afforded dicyclocalkenopyridines with two α-arylidene groups in good yields. In similar reaction conditions, 1-tetralone, which has only one α-methylene
