Ru-catalyzed oxidative coupling of allyl alcohols and activated olefins has been developed by C(allyl)-H activation of allyl alcohols providing efficient and direct access to synthetically useful α,β-unsaturated enone intermediates. Synthetic utility of this method was demonstrated by its application to synthesis of bioactive natural products such as Hydroxy-β-sanshool, ZP-amide I, Chondrillin, Plakorin
烯丙醇的C(烯丙基)-H活化已开发出Ru催化的烯丙醇与活化烯烃的氧化偶联,可提供直接有效地获得合成上有用的α,β-不饱和烯酮中间体的途径。该方法在合成具有生物活性的天然产物(例如羟基-β-山梨醇,ZP-酰胺I,软骨素,白粉蛋白和(+)-顺式-索拉明A)中的应用证明了其实用性。
