structural motifs of drug and bioactive natural product molecules. In this study, a regioselective protocol for olefination and arylation of arene-tethered 1,2-diols and 1,3-diols has been developed using easily foldable acetal structures for attaching pyridine and nitrile directing groups. The method overcomes the steric hindrance effect of the short-chain diols and affords products in high yield and
芳烃束缚的二醇构成了一类有价值的药物和生物活性天然产物分子的结构基序。在这项研究中,使用易于折叠的缩醛结构来连接吡啶和腈导向基团,开发了芳烃束缚的1,2-二醇和1,3-二醇的烯化和芳基化的区域选择性方案。该方法克服了短链二醇的空间位阻效应,得到了高产率和区域选择性的产物。这种高效的级联催化已成功用于天然产物的合成,例如前胡醇、紫花苜蓿和marmesin。
