  A novel green and energy-efficient synthesis of 2,3-dihydro/spiroquinazolin-4(1H)-ones via three-component cyclo-condensation reaction involving isatoic anhydride, amines and aldehydes/ketones utilizing recyclable tartaric acid-SDS catalyst system has been achieved. With simple requirements of mechanical stirring or mechanochemical activation at room temperature and one of the shortest reported times as of yet, it is a significant improvement on previously described methods for the synthesis of such compounds. Moreover the catalyst system can also be efficiently applied in large-scale reactions which indicates the potential for applications in industry.
