2013 m. Nr. 3 The green synthesis of xanthenedione and dihydropyrimidone derivatives catalyzed by nanocrystalline solid acid catalysts
A simple highly versatile and efficient synthesis of xanthenedione and dihydropyrimidone derivatives is achieved through condensation reactions catalyst by nano-sulfated zirconia, nano-structured ZnO, nano-γ-alumina and nano-ZSM-5 zeolites. The optical properties of the nano-structured organic molecules were studied. The advantages of methods are short reaction times and milder conditions, easy work-up and purification of products by nonchromatographic methods. The catalysts can be recovered for subsequent reactions and reused without any appreciable loss of efficiency.
