The syntheses of some methoxy-substituted bicyclic lactams, of the types 3 and 4, are reported employing two different conditions for the Schmidt reaction of appropriate ketones and employing two different conditions for the Beckmann rearrangement of the corresponding ketoximes. The alkyl to aryl migration ratios of the reactions were determined by high-performance liquid chromatography analysis of
据报道,使用两个不同的条件进行适当酮的施密特反应,并使用两个不同的条件进行相应酮肟的贝克曼重排,合成了一些类型3和4的甲氧基取代的双环内酰胺。通过反应的高效液相色谱分析来确定反应的烷基与芳基的迁移比。讨论了所报告反应的机制,确定了所报告机制的某些局限性,并根据各种反应的结果提出了另一种机制。施密特反应和贝克曼重排反应的应用被用于合成一些3型和3型氯双环内酰胺。4。
