This study explores a Pd-catalyzed decarboxylative Heck-type Csp3–Csp2 coupling reaction of 2,5-cyclohexadiene-1-carboxylic acid derivatives with vinyl halides to provide γ-olefination products. The olefinated 1,3-cyclohexadienes can be further oxidized to produce meta-alkylated stilbene derivatives. Additionally, the conjugated diene products can also undergo a Diels–Alder reaction to produce a bicyclo[2
这项研究探索了Pd催化的2,5-环己二烯-1-羧酸衍生物与乙烯基卤化物的Pd催化的Heck型Csp 3 -Csp 2偶联反应,以提供γ-烯烃化产物。烯化的1,3-环己二烯可以进一步氧化以产生间烷基化的二苯乙烯衍生物。此外,共轭二烯产物还可以进行Diels-Alder反应,生成双环[2.2.2]辛二烯骨架。
