A simple, efficient synthesis of 3-arylmethyl-7,8-dihydro-6H-chromene-2,5-dione 4 from Baylis-Hillman adduct acetates derived from aromatic aldehydes and cyclohexane-1,3-diones under solvent-free conditions is described. Interestingly, when Baylis-Hillman adducts derived from aliphatic aldehydes were tested under the similar conditions, the unexpected stereoisomers 5 and 6 were obtained in moderate yields. A plausible mechanism for the formation of 4-6 is proposed.

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.
