  ABSTRACT: Silver triflate and copper(I) iodide cocatalyzed direct alkynylation and cyclization reaction of in situ formed N-iminoisoquinolinium ylides with bromoalkynes is described. The reaction proceeds efficiently through a combination of C-H activation and subsequent tandem reaction in one pot, leading to diverse H-pyrazolo[5,1-a]isoquinolines in good yields under mild reaction conditions.

  ABSTRACT: A silver triflate and palladium acetate co-catalyzed reaction of N'-(2-alkynylbenzylidene)hydrazide with N-allyl ynamide is described, which generates 2-amino-H-pyrazolo[5,1-a]isoquinolines in good to excellent yield. The transformation proceeds with high efficiency through 6-endo cyclization, [3 + 2] cycloaddition, 3,3-sigmatropic rearrangement, and aromatization.
