into ketones was achieved using 0.1 mol % of MnCl2 and 4,4′,4′′‐tri(tert‐butyl)‐2,2′:6′,2′′‐terpyridine (tBu‐terpy) in the presence of mCPBA. Conversion of methyl ethers into ketones was particularly efficient and chemoselective. Electron‐deficient oxygen functionalities survived under the reaction conditions. The present method broadens the utility of methyl ethers as stable protective groups for hydroxy
带我走!直接Ç 烷基醚成酮h的氧化,使用0.1摩尔%的MnCl的实现2和4,4',4'' -三(叔丁基)-2,2':6',2'' -三联吡啶(t电池)在m CPBA的情况下。甲基醚向酮的转化特别有效且具有化学选择性。缺电子的氧官能团在反应条件下得以幸存。本方法扩大了甲基醚作为用于羟基官能团的稳定保护基和作为羰基化合物的前体的用途。
