An efficient and mild visible-light-enabled reaction involving the oxidative ring expansion of indoles with amidines in the aqueous phase at room temperature is developed. Benzo[1,3,5]triazocin-6(5H)-ones and quinazolinones were facilely obtained as the terminal products by using 2-substituted indoles and substituent-free indoles as substrates, respectively. This protocol features mild conditions, excellent functional group tolerance, and moderate to good yields.

可见光诱导的含am的吲哚氧化环扩环†

在室温下，开发了一种有效且温和的可见光使能的反应，该反应涉及吲哚与with在水相中的氧化环膨胀。以2-取代的吲哚和无取代的吲哚为底物，可以容易地获得苯并[1,3,5]三唑啉-6（5 H）-酮和喹唑啉酮作为终产物。该方案具有温和的条件，出色的官能团耐受性和中等至良好的产量。
