Paragraph 0034-0037, (2020/05/30)
The invention discloses a synthesis method of a quinoxaline heterocyclic derivative. An intermolecular redox reaction and a condensation cyclization reaction are carried out on an o-nitroaniline compound and an o-diol compound under the action of a water-soluble alkali to prepare the quinoxaline heterocyclic derivative in one step. Expensive transition metal catalysts and ligands do not need to beused, the water-soluble alkali is used as an accelerant and can be removed in a water washing manner, so that the product has no transition metal residue, the product is easy to separate, the recovery rate is high, and the method is simple in condition, easy to operate and low in equipment requirement; and the water-soluble alkali is used as the accelerant, so the unique byproduct is water, the atom economy is high, and the method has good research and industrial application prospects.
