چکیده
A facile one-pot multicomponent protocol for the synthesis of bio-active dihydropyrano(2,3-c)pyrazole derivatives from ethyl acetoacetate, hydrazine hydrate, malononitrile and aryl aldehydes using preheated-fly-ash as catalyst for the first time.These environmentally begin multicomponent cyclocondensations offer some interesting advantages, advantages of this methodology are the use of nontoxic solvent, cost-effective and easy availability of catalyst, ease of the work-up, high yields (up to 95%), and green protocol.
