Abstract
|
In this work, SBA-15/PrN(CH2PO3H)2 as a novel and heterogeneous catalyst containing of phosphorous acid groups was fully characterized by using various analysis techniques. A good range of novel pyrido[2,3-d]pyrimidines and pyrimido[4,5-b]quinolines were synthesized in the presence of SBA-15/PrN(CH2PO3H)2 under solvent-free condition. The major advantages of the described method are high yields, short reaction times and reusability of the catalyst. The obtained results from this research will be supported by the idea of rational designs, syntheses and applications of task-specific catalysts and molecules for the development of biomimetic anomeric based oxidation and/or aromatization mechanism.
