This manuscript describes the synthesis of γ-lactam from the nitrogen insertion reaction of cyclobutanones using an oxime as an aminating reagent with a catalytic amount of Brønsted acid. This method was employed with a more stable oxime reagent, which is a precursor analog of hydroxylamine derivatives with explosive properties. The reaction was tolerated by various substituted cyclobutanones and less
该手稿描述了使用肟作为胺化试剂和催化量的布朗斯台德酸,通过环丁酮的氮插入反应合成 γ-内酰胺。该方法采用更稳定的肟试剂,它是具有爆炸性的羟胺衍生物的前体类似物。各种取代的环丁酮和张力较小的五元或六元酮都可以耐受该反应。所得γ-内酰胺产物可通过开环水解转化为γ-氨基丁酸衍生物。从同位素效应等角度讨论了反应机理。
