and practical electrochemical method for selective reduction of cyclic imides has been developed using a simple undivided cell with carbon electrodes at room temperature. The reaction provides a useful strategy for the rapid synthesis of hydroxylactams and lactams in a controllable manner, which is tuned by electric current and reaction time, and exhibits broad substrate scope and high functional group
已经开发了一种使用室温下带有碳电极的简单的不分隔电池来选择性还原环状酰亚胺的高效实用的电化学方法。该反应为通过控制电流和反应时间调节的可控方式快速合成羟基内酰胺和内酰胺提供了有用的策略,并且具有宽泛的底物范围和对还原敏感部分的高官能团耐受性。最初的机械研究表明,该方法在很大程度上依赖于能够生成α-氨基烷基自由基的胺(例如i- Pr 2 NH)的利用。该方案为在温和条件下以高化学选择性裂解C–O键提供了一条有效途径。
