of perimidines with sodium azide in PPA. The corresponding amides were synthesized by acylation and were also obtained by the Schmidt reaction from 6(7)-acetyl(or benzoyl)perimidines. A special feature of the structure of the 2-substituted amines and amides is the presence of annular tautomerism slow in NMR time.

叠氮化物的方法。相应的酰胺通过酰化反应合成,也可以通过Schmidt反应从6(7)-乙酰基(或苯甲酰基)过亚
吡啶中获得。2-取代的胺和酰胺的结构的一个特殊特征是在NMR时间内慢速出现的环状互变异构现象。
