Molecular editing such as insertion, deletion, and single atom exchange in highly functionalized compounds is an aspirational goal for all chemists. Here, we disclose a photoredox protocol for the replacement of a single fluorine atom with hydrogen in electron-deficient trifluoromethylarenes including complex drug molecules. A robustness screening experiment shows that this reductive defluorination
在高度官能化的化合物中进行分子编辑,例如插入、删除和单原子交换,是所有化学家的理想目标。在这里,我们公开了一种光氧化还原方案,用于在缺电子的三氟甲基芳烃(包括复杂的药物分子)中用氢替换单个氟原子。稳健性筛选实验表明,这种还原性脱氟可以耐受生物活性分子中常见的一系列官能团和杂环。初步研究暗示了一个催化循环,其中有机光催化剂的激发态被氢原子供体还原淬灭,并被三氟甲基芳烃恢复到其原始氧化态。
