efficient strategy for the synthesis of γ-lactams has been reported. The hydroxylamines form Lossen rearrangement products of electron-deficient group migration with base and then undergo [3+2] cycloaddition reaction with vinyl cyclopropane, which could be performed with broad substrate scope, excellent functional group tolerance and high efficiency to produce the desired products. It also allowed further modification
已经报道了一种通用且有效的合成γ-内酰胺的策略。
羟胺与碱形成缺电子基团迁移的Lossen重排产物,然后与
乙烯基环丙烷发生[3+2]环加成反应,该反应底物范围广,官能团耐受性好,效率高,可生成所需产物。它还允许对这些 γ-内酰胺的其他衍
