three-component coupling of allylstannane, allyl chloride and a functionalized diene is described. Regioselective 1,4-functionalization of the Michael acceptor 1,3-diene is accomplished by the amphiphilic bis-π-allylpalladium complex. To the best of our knowledge, this is the first time a functionalized 1,3-butadiene has been used as a Michael acceptor. The scope of the present strategy is further extended to 1
描述了钯催化的烯丙基锡烷、烯丙基氯和官能化二烯的三组分偶联。迈克尔受体 1,3-二烯的区域选择性 1,4-官能化由两亲性双-π-烯丙基钯配合物完成。据我们所知,这是第一次使用功能化的 1,3-丁二烯作为迈克尔受体。本策略的范围进一步扩展到功能化二烯的 1,4-烯丙基化-氧基烯丙基化。
