| titleOfInvention | Green synthesis method of polysubstituted quinazoline derivative |
| abstract | The invention discloses a green synthesis method of a polysubstituted quinazoline derivative. The method comprises the following steps: taking a compound shown in a formula II and a methyl aromatic nitrogen heterocyclic compound as raw materials, mixing and reacting in the presence of ammonium acetate by taking copper salt as a catalyst, oxygen as an oxidant and organic acid as an activator to obtain a target product. The synthesis method avoids the use of complex substrates and strong oxidants, has the advantages of simple and easily-obtained reaction raw materials, environment-friendly reaction process, good substrate applicability, good functional group tolerance and high separation yield under the optimal condition. |
