摘要:描述了通过knoevenagel加合物去共轭烷基化/ Heck反应合成碳环的简单平台.knoevenagels加合物的去共轭烷基化有两个合成的可能,因为(1)由于knoevenagel加合物的碳负离子易于产生,Cc键的形成很简单,并且(2)导致烯烃迁移,这为环化反应提供了可能.此外,宝石-可降解部分用作合成操作的官能团.

摘要:The present disclosure relates to a novel method for preparing an arylnaphthalene lignan compound. In synthesis of arylnaphthalene lignan compounds and derivatives according to the present disclosure, a naphthalene backbone may be constructed first and an aryl group may be introduced at the final stage. Through this, various kinds of derivatives that could not be prepared from the existing methods can be synthesized effectively. Further, the synthesis method according to the present disclosure is appropriate for large-scale production.
