  Route to Pyrazolo[5,1-a]isoquinolines via a Copper-Catalyzed Tandem Reaction of 2-Alkynylbromobenzene with Pyrazole

  摘要：

  A copper-catalyzed tandem reaction of 2-alkynylbromobenzene and pyrazole is described that provides a facile route to pyrazolo[5,1-a]isoquinolines in good yields. During the reaction process, copper(1)-catalyzed hydroamination and C-H activation are involved.

  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.

  AbstractA novel and efficient route for the generation of H‐pyrazolo[5,1‐a]isoquinolines via silver triflate‐catalyzed one‐pot tandem reaction of 2‐alkynylbenzaldehyde, sulfonohydrazide, and ketone or aldehyde is described. This reaction proceeds with good functional group tolerance under mild conditions with high efficiency and excellent selectivity.
