A valuable and direct method to access 2-substituted-2-phenyloxetanes by electrophilic quenching of the corresponding 2-lithiated derivative has, for the first time, been described. 2-Lithiated-2-phenyloxetane was found to be configurationally unstable. Evidence is presented to show that electron-transfer processes are also operative in the coupling reactions with electrophiles.
首次报道了一种通过相应2-锂代衍生物的亲电猝灭来制备2-取代-2-苯基氧杂环丁烷的有价值且直接的方法。研究发现,2-锂代-2-苯基氧杂环丁烷在构型上是不稳定的。提供了证据表明,在亲电试剂参与的偶联反应中,电子转移过程同样起着作用。
