A facile and efficient cyclization of homotryptamines and their derivatives has been established for the construction of 4a‐chlorotetrahydropyrido[2,3‐b]indoles and 3,3‐spirocyclic 3H‐indoles using hypervalent iodine (1‐chloro‐1,2‐benziodoxol‐3‐one) under mild conditions. The broad substrate scope and successful gram‐scale experiment grant this metal‐free transformation great potential for further
已经建立了使用高价碘(1-氯-1,2-二甲基吡啶)构建4a-氯四氢吡啶并[2,3-b]吲哚和3,3-螺环3 H-吲哚的简便高效的环类胺及其衍生物的环化方法。苯并三唑-3-酮)在温和的条件下使用。广泛的基体范围和成功的克级实验为这种无金属的转化提供了进一步应用的巨大潜力。
