of unactivated alkenes has been established by using readily accessible 1‐azido‐1,2‐benziodoxol‐3(1H)‐one (ABX) as an azidating reagent, which affords a wide variety of structurally diverse 3‐N3‐substituted piperidines in good yields with excellent enantioselectivity. The reaction features good functional‐group compatibility and mild reaction conditions. Notably, both an electrophilic azidating reagent
通过使用容易获得的1-叠氮基-1,2-苯并恶唑醇-3(1 H)-1 (ABX)作为叠氮化试剂建立了未活化烯烃的第一个Pd催化对映选择性叠氮化反应,提供了多种结构多样的3‐N 3‐取代的哌啶具有良好的收率和出色的对映选择性。该反应具有良好的官能团相容性和温和的反应条件。值得注意的是,亲电子的叠氮化试剂和空间庞大的手性吡啶基-恶唑啉(Pyox)配体对于成功进行反应都是至关重要的。
