oxygen‐mediated drug release. Even though 1,2‐diaryloxyethenes look very simple, their synthesis was not an easy task. Previous methods are limited to symmetric molecules, lengthy step and low yield. We report on a facile synthetic method not only for 1,2‐diaryloxyethenes but also their sulfur and nitrogen analogs in yields ranging from 40 to 90% with more than 90% purity at the vinylation reaction
1,2-二芳氧基乙烯最近被提议作为单线态氧介导的药物释放的连接体。尽管 1,2-二芳氧基乙烯看起来非常简单,但它们的合成并非易事。以前的方法仅限于对称分子、冗长的步骤和低产率。我们报告了一种简便的合成方法,不仅可以用于 1,2-二芳氧基乙烯,还可以用于它们的硫和氮类似物,收率范围为 40% 至 90%,在乙烯基化反应中纯度超过 90%。
