This work demonstrates a green and efficient method to prepare 1,3-enynes via Pd(II)-catalyzed direct dehydrogenative olefination of terminal arylalkynes with unactived allylic ethers. Various terminal arylalkynes can participate in the reaction, stereoselectively affording the desired conjugated (Z)-1,3-enynes in moderate to good yields.
这项工作证明了一种绿色有效的方法,可通过Pd(II)催化末端芳基炔烃与未反应的烯丙基醚的直接脱氢烯化反应来制备1,3-烯炔。各种末端芳基炔烃可以参与反应,以中等至良好的产率立体选择性地提供所需的共轭(Z)-1,3-烯炔。
