[reaction: see text] Anodic intramolecular cyclization of alpha-(phenylthio)acetamides using a fluoride ion mediator was realized. Under ultrasonic irradiation, cyclization was accelerated markedly to give desired cyclized products in moderate to good yields. The local heating effect of ultrasonic irradiation seems to be more advantageous than usual heating.

氟离子介体实现了α-(苯
硫基)乙酰胺的阳极分子内环化。在超声辐射下,明显加速了环化反应,以中等至良好的产率得到了所需的环化产物。超声辐射的局部加热效果似乎比常规加热更有利。
