The O-arylation of o-enaminone functionalized phenols, namely, (E)-3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-ones, has been achieved via a self-promoted process in the presence of CuI, which provided a class of new biaryl ethers bearing a reactive enaminone fragment. The reactions were performed under mild conditions and the functionalized biaryl ether products have been found as useful building blocks for the assembly of heterocyclic compounds.
在 CuI 的存在下,通过自促进过程实现了邻烯氨基酮官能化苯酚(即 (E)-3-(dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-ones) 的 O-芳基化,从而提供了一类带有活性烯氨基酮片段的新型双芳基醚。反应是在温和的条件下进行的,功能化的双芳基醚产品被发现是组装杂环化合物的有用构件。
