## Abstract A novel series of 2‐hydroxy‐12‐aryl‐8,9,10,12‐tetrahydrobenzo[__a__]xanthene‐11‐ones were synthesized by the one‐pot multicomponent condensation of 2,7‐dihydroxynaphthalene, aromatic aldehydes, and cyclic 1,3‐dicarbonyl compounds in the presence of a catalytic amount of __p__‐toluenesul
## Abstract Some novel 12‐aryl‐12__H__‐benzo[__i__][1,3]‐dioxolo[4,5‐__b__]xanthene‐6,11‐diones can be rapidly and efficiently synthesized in excellent yields by condensing a variety of aldehydes with 3,4‐methylenedioxyphenol and 2‐hydroxy‐1,4‐naphthoquinone in the presence of a catalytic amount of
