| titleOfInvention | Method for synthesizing symmetrical 2,3,5, 6-tetra-substituted pyridine |
| abstract | The invention relates to a synthetic method of symmetrical 2,3,5, 6-tetra-substituted pyridine. The synthesis method comprises the steps of carrying out multi-step coupling, cyclization and aromatization reaction on a substituted acetonitrile compound, an aryl boric acid compound and dimethyl sulfoxide by taking a palladium source compound as a catalyst, so as to prepare the symmetrical 2,3,5, 6-tetra-substituted pyridine compound. The method has the advantages of rich raw material sources, simple and convenient reaction operation, simple post-treatment, excellent product yield, high purity and the like, provides a brand-new synthesis method for preparing the polysubstituted pyridine compounds, and has good application value. |
