One-pot preparation of a variety of pharmacologically pertinent xanthone heterocycles has efficiently been achieved from their respective phenol compounds and salicylic acid/thiosalicylic acid in the presence of the catalytic amount of heteropoly acid. Most of the reactions showed high regioselectivity and produced xanthones/thioxanthones in good yields under microwave irradiation.

We describe the synthesis of some new hydroxythioxanthones by treatment of thiosalicylic acid (TSA) with various substituted phenols in the presence of Al2O3-CH3SO3H (AMA). Most of the reactions show high regioselectivity and produce thioxanthones in good yields.
