A strategy based on Pd-mediated ring closure of 1,2-disubstituted indoles containing an unactivated olefin leading to indole-1,2-fused 8- and 9-membered rings has been developed for the identification of new and potential scaffolds for apoptosis. A large number of fused indole derivatives containing an endocyclic double bond were synthesized using this robust methodology. A representative compound showed promising apoptotic properties in zebrafish embryos.
一种基于Pd介导的环闭合策略,针对含有未活化烯烃的1,2-二取代吲哚,引导形成吲哚-1,2-融合的8和9成员环,已被开发用于识别新的潜在凋亡骨架。利用这一高效的方法合成了大量含有内环双键的融合吲哚衍生物。一种代表性化合物在斑马鱼胚胎中显示出良好的凋亡特性。
