Natural Phosphate K09 as a New Reusable Catalyst for the Synthesis of Dihydropyrano[2,3-c]Pyrazole Derivatives at Room Temperature

Abstract : In this study, we report a simple, efficient and green protocol for the synthesis of pyrano[2,3-c]pyrazole derivatives by the use of the natural phosphate K09 as a mild and efficient heterogeneous catalyst. The catalytic efficiency of K09 was compared with other heterogeneous catalysts to determine the best catalyst for said conversion. Easy recovery of the catalyst and its reusability, room temperature reaction conditions, short reaction time, excellent yields, are some of the important features of this protocol.
