  • An efficient, Bi(NO3)3-Al2O3 catalyzed one pot three component synthesis of 6-amino-4-aryl-5-cyano-3-methyl-1-phenyl-1,4-dihydropyrano[2,3-c]pyrazoles via a reaction between 3-methyl-1-phenyl-2-pyrazolin-5-one, aromatic aldehydes and malononitrile is described. This method provides advantages such as high yield, shorter reaction time, mild reaction conditions, easy work-up procedure and operational simplicity.
