    • 4OMe-p], the precursor intermediate compound of product 3aa, was isolated with 65% yield by the reaction between azido-alkyne 4a and iodide 5a under the optimised reaction conditions except that no heating was performed and stirring was done at rt for 1.0 h. Interestingly, the elimination of CuI from this reaction afforded the intermediate D, albeit only with 16% yield even after stirring at rt for 14 h.
