A general method for the convergent assembly of polyether structures has been developed based on a NiII/CrII-mediated cross-coupling reaction of alkenyl iodides with aldehydes. The present method allowed coupling to oxane rings via acetal cyclization and reductive etherification reactions.
基于 NiII/CrII 介导的烯基碘化物与醛的交叉偶联反应,开发了一种聚合聚醚结构的通用方法。本方法允许通过缩醛环化和还原醚化反应与恶烷环偶联。
