synthetic strategy of 3-substituted 3-azido-1,3-dihydro-2H-indol-2-ones was realized through hydroazidation of phenacylideneoxindoles with azidotrimethylsilane under mild conditions. In the presence of tetrabutylammonium fluoride, the reaction proceeds by the anti-electron addition of N3. This azidation method of phenacylideneoxindoles is valuable in pharmaceutical synthesis and chemical biology studies
3-取代的 3-叠氮基-1,3-二氢-2H-吲哚-2-酮的简单合成策略是通过在温和条件下用叠氮基三甲基硅烷对苯亚基氧吲哚进行氢化反应实现的。在四丁基氟化铵存在下,反应通过N 3的反电子加成进行。由于反应条件温和,产物纯化简单,不受任何过渡金属残留物的污染,这种亚苯基氧吲哚的叠氮化法在药物合成和化学生物学研究中具有重要价值。
