A convenient and microwave-promoted novel protocol for the syntheses of diverse kinds of substituted benzopyrans from the corresponding variety of substituted hydroxy acetophenones and keto compounds using benzyltrimethylammonium hydroxide (Triton-B) under solvent-free conditions has been developed. This protocol is mild and efficient than the other reported methods.
