8-Aryl-7,8-dihydro-[1,3]dioxolo[4,5-g]chromen-6-ones were synthesized efficiently by a three components one-pot reaction of 3,4-methylenedioxyphenol, aromatic aldehydes and Meldrum acid in the presence of silica-bonded N-propyl sulfamic acid at 120 ℃ without solvent. The effects of temperature and amount of catalysts on the yields were investigated. All products were characterized by 1H NMR, 13C NMR, MS techniques and elemental analysis.

Key words: [1,3]dioxolo[4,5-g]chromen, 3,4-methylenedioxyphenol, Meldrum acid, silica-bonded N-propyl sulfamic acid, synthesis
