aryl allyl ethers derived from the phosphine-catalyzed addition of electron-deficient allenes with phenol are found to be efficient substrates for the synthesis of 2-substituted 2,3-dihydrobenzofurans and indolines. It is the first example of aryl allyl ether used as an ideal and practical precursor of hard to get functionalized 1,3-butadiene for the heterocyclic compound synthesis.
已经开发出高度区域和立体选择性的钯催化的官能化芳基烯丙基醚的多米诺反应。发现衍生自膦-催化的电子缺陷的烯与酚的加成反应的各种芳基烯丙基醚是合成2-取代的2,3-二氢苯并呋喃和二氢吲哚的有效底物。这是芳基烯丙基醚的第一个实例,它是难以获得用于杂环化合物合成的功能化1,3-丁二烯的理想且实用的前体。
