Allylic arylation of cinnamyloxyphenylboronic acid pinacol esters 3, which have arylboronic acid moiety and allylic ether moiety, using a hydrazone 1d–Pd(OAc)2 system proceeded and gave the corresponding 1,3-diarylpropene derivatives 4 with a phenolic hydroxyl group via a selective coupling reaction of the π-allyl intermediate to the boron-substituted position of the leaving group.
使用1d- Pd(OAc)2体系进行了具有芳基硼酸部分和烯丙基醚部分的肉桂氧基苯基硼酸频哪醇酯3的烯丙基芳基化反应,并通过选择性的反应得到了相应的带有酚羟基的1,3-二芳基丙烯衍生物4 π-烯丙基中间体与离去基团的硼取代位置的偶联反应。
