Al(DS)3.3H2O: as Catalyst for the Synthesis of 1,4-Dihydropyrano[2,3-c]pyrazole Derivatives abstract
A new method for the preparation of 1,4-dihydropyrano[2,3-c]pyrazole derivatives via the mixing of an aromatic aldehyde, malononitrile and 5-methyl-2-phenyl-2,4-dihydro-3H pyrazol-3-one in the presence of Al(DS)3.3H2O as a catalyst was reported. The corresponding products were obtained in high yields (82–88 %).
