A novel regio‐ and diastereoselective iron‐catalyzed intermolecular oxyazidation of enamides using various azidobenziodoxolone (ABX) derivatives is presented. A variety of α‐N3 amino derivatives and of α‐N3 piperidines were synthesized in good yields and under mild reaction conditions. The reaction involves a radical process using cheap FeCl2 as the initiator.
提出了一种新颖的区域和非对映选择性铁催化的酰胺,使用各种叠氮苯并齐多唑酮(ABX)衍生物进行分子间氧化。各种α-N的3氨基衍生物和α-N的3个哌啶以良好产率和温和的反应条件下合成的。该反应涉及使用廉价的FeCl 2作为引发剂的自由基过程。
