Glycerol mediated, one pot, multicomponent synthesis of dihydropyrano[2,3-c]pyrazoles Sohal, Harvinder Singh Goyal, Arun Sharma, Rajeev Khare, Rajshree Kumar, Sanjay Glycerol Aldehydes Catalyst free Malononitrile Pyrazol-5-one Dihydropyrano[2 3-c]pyrazole Multi component, one pot synthesis of various dihydropyrano[2,3-c]pyrazole derivatives from the condensation of ethyl acetoacetate, hydrazine, aromatic aldehyde and malononitrile has been described using glycerol, as environmentally benign, economical, and easily available solvent. The targeted molecules are obtained in excellent yield without use of any additional catalyst.
