Preparation process and application of oxygen dinitrogen heterocyclic compound
-
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.

The non-symmetric electrophilic diazenes 2 and 3 react with 1-aminocyclopentenes 1 giving enamine adducts exclusively, which have been isolated in some cases; on hydrolysis, the hydrazine substituents in the monoadducts from 2 is cleaved and only α,β-unsa

In the title ring system, the benzylic nitrogen (N7), whether substituted or not, is abnormally unreactive.Hydrolysis of the di-urethanes 3a or b occurs readily at N6 to give 10a or b, but not at all at N7.In 3d Pd-H2 remo
