| titleOfInvention | Preparation method of 3-amino-5-alkylisoxazole |
| abstract | The invention discloses a preparation method of 3-amino-5-alkylisoxazole, which is completed by two steps and belongs to the technical field of organic chemistry. Starting from easily available aldehyde, adding acetonitrile in the presence of metal alkali to obtain an intermediate hydroxyl nitrile, reacting with hydroxylamine, and performing ring closure reaction in the presence of Lewis acid for autoxidation to obtain the 3-amino-5-alkyl isoxazole. Raw materials are common in the reaction, chloroform or carbon tetrachloride in the traditional method is avoided, and the method has potential industrial amplification prospect. |
