Abstract:
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.
Keywords:
Xanthone, heteropoly acid, thioxanthone, green chemistry, salicylic acid, thiosalicylic acid.
