摘要

Abstract Three-component one-pot synthesis of some novel 12-aryl-12H-benzo[i][1,3]dioxolo[4,5-b]xanthene-6,11-diones involving treatment of 3,4-methylenedioxyphenol, aldehydes, and 2-hydroxy-1,4-naphthoquinone in presence of HClO₄–SiO₂ was achieved, and this reaction was extended to preparation of 10-aryl-6,7,8,10-tetrahydro-7,7-dimethyl-9H-[1,3]dioxolo[4,5-b]xanthen-9-ones by three-component reaction of 3,4-methylenedioxyphenol, aldehydes, and dimedone.
