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.

The nanoporous framework of a cyclodextrin nanosponge was used as catalyst for accelerating the one-pot, three-component reaction of dimedone, aldehyde, and phenols for synthesis of xanthene derivatives. Moreover, the nanocavities of cyclodextrin nanosponges were exploited for immobilization of heteropolyacids through the wet impregnation method. This catalyst exhibited superior catalytic performance
