Lynchpins comprising α-silyl amides have been validated for type I anion relay chemistry (ARC) to permit ready access to γ-ketoamides. Importantly, the ARC protocol can be run at ambient temperature without the need of additional reagents to trigger the [1,4] Brook rearrangement.
包含α-硅基酰胺的连接键已被验证可用于 I 型阴离子中继化学(ARC),以方便获得γ-酮酰胺。重要的是,ARC 反应可以在环境温度下进行,无需额外的试剂来引发[1,4]Brook 重排。
