Embodiment 1
[0017] First add 3-trifluoromethylphenyl azide (0.1mmol) to the round bottom flask, then add tetramethylguanidine (0.3mmol), stir evenly, and then add dimethyl acetonyl phosphonate (0.1mmol) , and then stirred and reacted at 80°C for 12h, and the whole reaction process was detected by TLC until the reaction was completed. Finally, the crude product was extracted with water and ethyl acetate, dried with anhydrous magnesium sulfate, and then separated by silica gel column to obtain the pure product with a yield of 92%.
Embodiment 2
[0019] First add 4-bromophenyl azide (0.1mmol) to the round bottom flask, then add tetramethylguanidine (0.3mmol), stir evenly, then add dimethyl acetonyl phosphonate (0.1mmol), and then add The reaction was stirred at 80° C. for 16 h, and the whole reaction process was detected by TLC until the reaction was completed. Finally, the crude product was extracted with water and ethyl acetate, dried with anhydrous magnesium sulfate, and then separated by silica gel column to obtain the pure product with a yield of 91%.
Embodiment 3
[0021] First add 4-methoxyphenyl azide (0.1mmol) to the round bottom flask, then add tetramethylguanidine (0.3mmol), stir evenly, then add dimethyl acetonyl phosphonate (0.1mmol), After that, the reaction was stirred at 80° C. for 24 h, and the whole reaction process was detected by TLC until the reaction was completed. Finally, the crude product was extracted with water and ethyl acetate, dried with anhydrous magnesium sulfate, and then separated by silica gel column to obtain the pure product with a yield of 63%.
