Abstract

The invention discloses a heterocyclic ring aromatic ether compound and a synthesis method thereof, and belongs to the technical field of organic synthesis. The heterocyclic ring aromatic ether compound is mainly characterized in that the heterocyclic ring aromatic ether compound has the following structure general formula shown as the accompanying drawing, wherein R1 and R2 are correspondingly and respectively shown as follows: (1) R1 H, and R2 is H; (2) R1 is H, and R2 is Me; (3) R1 is Me, and R2 H. The invention concretely discloses the synthesis method of the heterocyclic ring aromatic ether compound. A mixed solution of acetic anhydride and acetic acid is used for replacing peroxyacetic acid or trifluoromethanesulfonic acid with high corrosiveness; the operation is safer and easier; the industrial production is facilitated; in addition, the heterocyclic ring aromatic ether compound is obtained through oxidizing 4-pyridone by iodonium oxidizing agents.

Description

technical field

[0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a heterocyclic aromatic ether compound and a synthesis method thereof. Background technique

[0002] Present typical method for synthesizing trivalent iodine oxidizing agent:

[0003] 1, synthesize trivalent iodine oxidant (document 1-3) with peroxyacetic acid oxidation iodine benzene compound, concrete reaction process is:

[0004]

[0005] 2, in the presence of trifluoromethanesulfonic acid, the trivalent iodine oxidant (document 4) is synthesized with sodium perborate oxidation iodobenzene compounds, and the concrete reaction process is:

[0006]

[0007] Although the above-mentioned method for synthesizing trivalent iodine oxidant is very effective, strong corrosive acid peracetic acid or trifluoromethanesulfonic acid is used in the synthesis process, and there are potential safety hazards in the operation process, which is not conducive to indust...
