摘要：

Pyrano pyrazoles are synthesized by hydrazine hydrate, ethyl acetoacetate, aromatic aldehyde and malononitrile using grinding method with calcinized eggshell catalyst. The calcinized eggshell catalyst was obtained from chicken eggshell waste. The calcinized eggshell is a safe, naturally available and inexpensive catalyst with high catalytic efficiency. The short reaction time, high yield, easy work-up, grinding technique, room temperature, solvent free, mild reaction condition and reusability of the catalyst are the advantages of this method. The scope of this reaction was to develop multicomponent organic reaction by using green catalyst at room temperature. The products were characterized by IR, H-1 NMR, C-13 NMR and GC-MS techniques.
