Abstract :
Starch solution has been used as an eco-friendly catalyst for the synthesis of dihydropyrano[2,3-c]pyrazoles via the four-component one-pot reaction between arylaldehydes, hydrazine monohydrate , ethyl acetoacetate and malononitrile at thermal condition. This method provides several advantages such as environmental friendliness, short reaction time, excellent yields and simple workup procedure.
