title: Silver triflate-catalyzed three-component reaction of 2-alkynylbenzaldehyde, sulfonohydrazide, and alpha,beta-unsaturated carbonyl compound.
abstract: A highly efficient silver triflate-catalyzed three-component reaction of 2-alkynylbenzaldehyde, sulfonohydrazide, and alpha,beta-unsaturated carbonyl compound is reported, which affords H-pyrazolo[5,1-a]isoquinoline-1-carboxylates in good yield.
