A combination of carboxymethylpullulan (CMP) and Cu2O has been developed as a highly efficient catalytic system for the Huisgen-click reaction. Our results indicate that the acidic CMP could be used for 6 cycles without decreasing the activatin

The invention discloses a preparation method of 1,2,3-triazole compound and belongs to the field of medicament catalyzed synthesis technology. The technical scheme is characterized in that according to the preparation method of the 1,2,3-triazole compound, an end group alkyne compound and organic trinitride are respectively used as raw materials; pullulan triazole/cuprous chloride is used as a catalytic system; water is used as a solvent; the 1,2,3-triazole compound is prepared through mixed stirring reaction under the condition of the room temperature of minus 100 DEG C. According to the preparation method, pullulan polymer cotaining triazole group is applied to Huisgen cycloaddition reaction to be used as an additive to stabilize cuprous ions so that use level of catalyst in the catalytic reaction process is reduced. The catalytic system is mainly subjected to catalytic reaction in water, simple, reliable, high in yield, easy to separate, reusable, green, environmentally friendly, and the like.

A thermally promoted and CuSO4-catalyzed new version of the Huisgen-click reaction is presented in this Letter. Notably, this protocol was suitable not only for the reactions between organic azides and alkynes, but also for one-pot three-component reactions among alkyl halides, NaN3, and alkynes.
