Photocatalysis method for preparing polysubstituted quinoxaline in water-containing medium

The invention provides a photocatalysis method for preparing polysubstituted quinoxaline in a water-containing medium, and belongs to the technical field of organic synthesis. The method comprises the following steps: by taking R1-substituted quinoxaline and R2-substituted benzoylformic acid as raw materials, putting a photocatalyst, an oxidant, an additive and a water-containing solvent into a reaction tube, and irradiating for 12 hours at room temperature under a blue light illumination condition, thereby obtaining the product polysubstituted quinoxaline derivative. The iridium complex is adopted as a photosensitive catalyst, decarboxylation acylation reaction is directly carried out in a water-containing medium, the method has the advantages of being mild in reaction condition, high in yield and the like, and new method guidance is provided for preparation of the compound.

PIDA-mediated intramolecular oxidative C-N bond formation for the direct synthesis of quinoxalines from enaminones

A intramolecular oxidative C(sp2)-N bond formation mediated by hypervalent iodine(iii) to obtain quinoxalines from readily available N-(2-acetaminophenyl)enaminones was developed. A tandem process involving PIDA-mediated intramolecular condensation cyclization and a subsequent elimination was postulated, which was highly efficient and metal-free under mild conditions. Moreover, flexible structural modifications of quinoxalines bearing carbonyl groups are of interest for further transformations as building blocks in organic synthesis.
