A novel and efficient method for the synthesis of new hydroxythioxanthone derivatives

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.

A green and regioselsctive synthesis of xanthone and thioxanthone derivatives in the presence of heteropoly acid under microwave irradiation

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.
