An efficient aryl to vinyl 1,4‐palladium migration/Heck sequence was developed for the stereoselective synthesis of 1,3‐dienes. High stereoselectivity was observed not only for 1,3‐dienes bearing two similar aryl groups at terminal positions, but also for those with configurations shown to be unfavorable with previous methods.
开发了一种有效的芳基到乙烯基1,4-钯迁移/ Heck序列,用于1,3-二烯的立体选择性合成。不仅对于在末端位置带有两个相似芳基的1,3-二烯,还观察到了较高的立体选择性,而且对那些构型显示不利于先前方法的化合物也观察到了高立体选择性。
