Paragraph 0025; 0026, (2018/07/30)
The invention provides a preparation process and application of an oxygen dinitrogen heterocyclic compound. The preparation process includes: enabling N-carbalkoxy hydrazine and disubstituted ether tobe in cyclization reaction under action of alkali to obtain a N-carbalkoxy oxygen dinitrogen heterocyclic compound; enabling the N-carbalkoxy oxygen dinitrogen heterocyclic compound to be in deprotection reaction with the alkali to obtain the oxygen dinitrogen heterocyclic compound. A new N-protection strategy is used, so that consumption of expensive protection agents is avoided, and reaction yield is increased. In addition, the preparation process has the advantages that three wastes are few, operation is simple and equipment is less prone to corrosion, and is conducive to industrial production.
