Abstract Palladium-catalyzed synthesis of 2H-pyrano[2,3-g]isoquinolinones have been described from easily accessible precursor 6-cyanoumbelliferone triflate via sequential of Sonogashira coupling and the following annulations with several primary alkylamines under basic conditions The so obtained 6-propargylamino-2H-pyrano[2,3-g]isoquinolinones were involved in the CuAAC reaction with 2-azidobenzoic
Palladium-Catalyzed Cross-Coupling Reactions of 1,2-Diiodoalkenes with Terminal Alkynes: Selective Synthesis of Unsymmetrical Buta-1,3-diynes and 2-Ethynylbenzofurans
for the preparation of unsymmetricalbuta-1,3-diynes and 2-ethynylbenzofurans. In the presence of palladium(II)acetate and copper(I) iodide, unsymmetrical buta-1,3-diynes wereselectively obtained in moderate to good yields. Moreover, 2-ethynylbenzofuranswere obtained in one pot from the reaction of 2-ethynylphenol with( E)-1,2-diiodoalkenes, palladium(II)acetate, and copper(I) iodide by simple heating
