arylative isomerization of allyl alcohols, a milder and regioselective access to the versatile building blocks β-aryl aldehydes and ketones was developed. This new and chelation-controlled protocol enabled the compatibility of wide range of functionalities to generate dihydrochalcones, α-benzyl-α′-alkyl acetones, dihydrocinnamaldehydes, and α-benzyl β-keto esters (from Baylis–Hillman adducts). A practical
通过在 PdII 介导的烯丙醇芳基化异构化中使用配体,开发了一种更温和和区域选择性的通用构建块 β-芳基醛和酮。这种新的螯合控制方案使广泛的功能兼容,以生成二氢查耳酮、α-苄基-α'-烷基丙酮、二氢肉桂醛和 α-苄基 β-酮酯(来自 Baylis-Hillman 加合物)。还展示了普罗帕酮中间体的实用多克合成。
