摘要：

In this work, disulfonic acid imidazolium chloroaluminate {[Dsim]AlCl4} is applied as a new acidic and heterogeneous catalyst for green, simple and efficient synthesis of 6-amino-4-(4-methoxyphenyl)-5-cyano-3-methyl-1-phenyl-1,4-dihydropyrano[2,3-c]pyrazoles by the one-pot multi-component condensation of aryl aldehydes with ethyl acetoacetate, malononitrile and hydrazine hydrate at 80 degrees C under solvent-free conditions.
