Pseudo six-component process for the synthesis of tetrahydrodipyrazolo pyridines using Ionic liquid immobilized on FeNi۳ nanocatalyst

چکیده مقاله

A highly efficient method for the synthesis of tetrahydrodipyrazolopyridines by a multicomponent reaction of ethyl acetoacetate, an aldehyde, hydrazine and ammonium acetate using an ionic liquid (IL) supported on a FeNi3 nanocatalyst is described. This method provides several advantages including mild reaction conditions, applicability to a wide range of substrates, reusability of the catalyst and little catalyst loading.
