Preparation method of nitrogen-containing heterocyclic compound

[0110] Example 1 product 1-1

[0111] Under nitrogen protection, 4-propylphenylacetylene (0.5mmol), perfluoroiodobutane (0.75mmol), TMSN 3 (1.0mmol), oxide TBPB (1.0mmol), solvent (2mL) and catalyst Fe(OTf) 3 (12.7mg, 0.025mmol) was placed in a dry reaction tube and reacted at 20°C for 20 minutes. After the reaction was completed, the solvent was removed by a rotary evaporator under reduced pressure, dissolved in toluene, continued to react at 120° C. for 10 minutes, and separated by column chromatography to obtain the product 1-1.

[0112] Embodiment 2 product 1-2~1-32

[0113] The preparation method of the product in this example is the same as that in Example 1, see Table 1 for the differences.

[0118] Products 1-27:

[0119] The preparation method is the same as the preparation method of product 1-1, the difference is:

[0120] After being dissolved in toluene, the reaction temperature was 110° C., and the reaction time was 15 minutes.

[0121] Products 1-28:

[0122] The preparation method is the same as the preparation method of product 1-1, the difference is:

[0123] After being dissolved in toluene, the reaction temperature is 130° C., and the reaction time is 5 minutes.

[0124] Products 1-29:

[0125] The preparation method is the same as the preparation method of product 1-1, the difference is:

[0126] Before dissolving by methanol, the reaction temperature in the reaction tube was -20°C, and the reaction time was 30 minutes.
