Abstract

A series of 2-hydroxy-7,8-dihydroquinolin-5(6H)-ones and 7,8-dihydroquinoline-2,5(1H,6H)-diones have been synthesized in good to excellent yields from Morita-Baylis-Hillman ­adduct acetates, cyclohexane-1,3-diones and ammonium acetate or primary amines in one pot under solvent-free conditions.
