  The Behaviour of Nitrilimines Towards Ethyl Isocyanoacetate

  摘要：

  Interactions between nitrilimines and the title isocyanide afford, through two competing pathways, 2,3-diliydro-1,2,4-triazines and 1,3-oxazoles. In situ cycloaddition of unreacted nitrilimine with the triazines gives rise to a third class of products, the bicyclic 1,5,6,8a-tetrahydro[1,2,4]triazolo[4,3-d][1,2,4]triazines. Acceptor-free representatives of the latter are prone to triazine ring cleavage, yielding triazolyl ketone hydrazones which served as a structure proof. Substituent effects became apparent upon employment of N-(4-methoxyphenyl)- and N-(4-nitrophenyl)nitrilimines: whereas the former afforded a quinoxaline as the fourth product, triazine formation was totally blocked with the latter, the corresponding oxazole being the sole product. The constitution of acceptor-substituted bicyclic compounds (which failed to give the structure-revealing hydrazones) was established by an X-ray diffraction analysis.

  4-triazolium salts 11 are formed. Compounds 11 with tert-butyl group at the ring are unstable too, giving rise to triazoles 13. Pyrazole formation (analogues of 14) is completely suppressed when both tert-butyl and aryl isocyanides are used, whereas access to this ring system works best with see-alkyl isocyanides (the influence of substituents of 2 being almost negligible in this case).

  已经发现四种标题化合物的形成强烈地依赖于取代基：1,2,3-三唑鎓盐6并非由具有与C-或N-苯基连接的电子受体的腈2产生。同样，叔丁基和芳基异氰酸酯不提供这类化合物。由前者的异氰化物得到季铵化产物7，而由后者的1,2,4-三唑鎓盐11得到。在环上具有叔丁基的化合物11也不稳定，从而产生三唑13。吡唑的形成（类似14）当两个被完全抑制叔丁基和芳基异腈的使用，而访问该环系统的工作原理最好看到烷基异氰化物（的取代基的影响2是在这种情况下几乎可以忽略）。由中间体1，2-二重氮基22通过扩环形成喹喔啉23非常受雇于使用在N-苯基上带有供体取代基的2，并且在此前提下，闭环22实际上与性质无关异氰化物。的形成23不与观察到2 有受体基团。
