Abstract
In this work, nano-AlPO4/Ti(IV) (NAPT) as a new nanocomposite was prepared and then characterized by FT-IR, XRD, FESEM, TEM, BET and TGA. This nano-catalyst was used for synthesis of dihydropyrano[2,3-c]pyrazole (DHPP) derivatives by one-pot four component reaction of aldehyde, ethyl acetoacetate, malononitrile and hydrazine hydrate. An uncomplicated work-up, high yields of product, short reaction times and use of low-cost catalyst are considerable properties of present procedure
