Described herein is a protocol for visible‐light‐induced consecutive synthesis of gem‐difluorinated spiro‐γ‐lactam oxindoles under mild conditions by means of a process involving sequential radical difluoromethylative dearomatization, hydroxylation, and oxidation. The protocol features high chemo‐ and regioselectivity, good functional group tolerance, and easy scalability. Several of the functionalized
本文描述的是在温和条件下通过涉及顺序自由基二氟甲基化脱芳香化,羟基化和氧化反应的过程,在可见光诱导下连续合成宝石-二氟化螺-γ-内酰胺基吲哚的规程。该协议具有较高的化学和区域选择性,良好的功能基团耐受性和易于扩展的特点。几种功能化的螺喔啉产品显示出良好的杀真菌活性,表明它们具有潜在的农用化学应用。
