Ultrasound-promoted One-pot Synthesis of 8-Aryl-7,8-dihydro-[1,3]-dioxolo[4,5-g]-quinolin-6(5H)-one Deriva tives under Catalyst-free and Solvent-free Conditions

摘要

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
