A metal-free and cost-effective synthesis protocol has been initially proposed for the construction of CF3-containing oxindoles via the direct oxidative trifluoromethylation of activated alkenes with Langlois’ reagent (CF3SO2Na). The present methodology, which utilizes very cheap CF3 reagent and a simple oxidant, provides a convenient and practical approach to CF3-containing oxindoles with a wide variety
最初已经提出了一种无金属且具有成本效益的合成方案,用于通过用Langlois试剂(CF 3 SO 2 Na)对活化的烯烃进行直接氧化三氟甲基化来构建含CF 3的羟吲哚。本方法利用非常便宜的CF 3试剂和简单的氧化剂,为含有CF 3的具有多种官能团的羟吲哚提供了方便实用的方法。
