A convenient, one-pot, solvent-free reaction of amines, aromatic aldehydes, and Meldrum's acid to form 8-aryl-7,8-dihydro-[1,3]dioxolo[4,5-g]quinolin-6- (5H)-one and 4-aryl-3,4-dihydroquinolin-2-(1H)-one in the presence of 10 mol% ZrOCl2 · 8H2O under ultrasonic irradiation is described. This new protocol offers several advantages including low catalyst loading, clean reaction, easy workup, use of recyclable and ecofriendly catalyst, short reaction times, good yields, and solvent-free conditions.

An ultrasound-accelerated one-pot procedure has been explored for the synthesis of 8-aryl-7,8-dihydro-[1,3]-dioxolo[4,5-g]quinolin-6(5H)-one derivatives using the reaction between 3,4-methylendioxyaniline 1, aldehyde 2 and isopropylidene malonate 3 under catalyst-free and solvent-free conditions. High yields of the products, mild reaction condition, environmentally friendly procedure, catalyst- and solvent-free conditions are the main advantages of this protocol.
