Diazoalkanes have been found to add to heterocyclic substituted Schiff bases (imines), providing a very useful route to the synthesis of the hitherto unknown heterocyclic substituted Δ-1,2,3-triazolines. The orientation of the addition as well as the results of synthesis accord with previously reported mechanistic considerations. The direction of dipole orientation and the structure assigned to the
已发现重氮烷烃可添加到杂环取代的席夫碱(亚胺)上,为迄今为止未知的杂环取代的Δ-1,2,3-三唑啉的合成提供了非常有用的途径。加料的方向以及合成的结果符合先前报道的机理考虑。核磁共振波谱法阐明了偶极取向的方向和分配给加合物的结构。
