    • 3 in the molar ratio 1:2:4}, 0.5 mmol of enyne and 2.5 mL of degassed toluene were introduced. The reaction mixture was then heated at 80 °C until complete conversion as observed by GC-MS and then 0.16 mL (1 mmol) of diethyl acetylenedicarboxylate (DEAD) was added to the crude reaction mixture, which was heated at 110 °C. The solvent was removed in vacuum and the crude product was purified by flash chromatography.
