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.
