The stereospecific synthesis of polyenes is of great synthetic value. Disclosed herein is a new, efficient, stereoconvergent approach for the synthesis of functionalized polyenes via a radical-mediated Heck-type alkylation. The easily accessed Z- and E-mixed alkenes are harnessed as starting material, leading to a unique stereoisomer of polyenes. In addition, the transformation features mild reaction
多烯的立体定向合成具有很大的合成价值。本文公开了一种新的,有效的,立体收敛的方法,用于通过自由基介导的Heck型烷基化来合成官能化的多烯。利用易于混合的Z和E混合烯烃作为起始原料,形成了独特的多烯立体异构体。另外,该转化具有温和的反应条件和广泛的官能团相容性。以有用的产率提供了各种有价值的1,3-二烯和1,3,5-三烯。
