An Efficient Synthesis of 2-Hydroxy-7,8-dihydroquinolin-5(6//)-ones and 7,8-Dihydroquinoline-2,5(l//,6/7)-diones from Morita-Baylis-Hillman Adduct Acetates

摘要

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