A variety of quinazolinones are readily prepared via one-pot three-component reaction in good to excellent yields. The desired products were obtained from the reaction of dimedone, various aldehydes with 2-aminobenzimidazole under mild reaction conditions using MCM- 41-SO3H as effective catalyst in green and reusable catalyst in refluxing ethanol has been developed. Starting from the corresponding available materials, this friendly and environmentally free-metal procedure has been successfully… CONTINUE READING
