چکیده مقاله :
An efficient one-pot four-component protocol for the synthesis of pyrano[2,3-c]pyrazolederivatives has been demonstrated using Y(NO3)3.6H2O as catalyst under mild condition. This isa general synthetic protocol which could be applicable to a wide range of carbonyl compoundsincluding aromatic aldehydes, isatins and acenaphthenequinone. All The reactions proceededsmoothly, high-yielding and purity via an easy work-up procedure.
