• An Environmentally Benign Synthesis of <i>cis</i>-2,6-Disubstituted Tetrahydropyrans via Indium-Mediated Tandem Allylation/Prins Cyclization Reaction

  DOI：10.1021/jo7016857

  日期：2008.1.1

  cis-2,6-disubstituted tetrahydropyrans in good yields. Evidence suggests that InI, formed upon aldehyde (R1CHO) allylation in aqueous media, acts as a promoter for the silyl-Prins reaction with the second equivalent of added aldehyde (R2CHO). The preparation of cyclohexenyl-fused pyrans via this one-pot, three-component coupling process is presented, as is a short formal synthesis of (±)-centrolobine

  在铟金属的存在下，3-碘-2-[（（三甲基甲硅烷基）甲基]丙烯（1）与顺序添加的醛反应，以良好的产率提供顺式-2,6-二取代的四氢吡喃。有证据表明，在水性介质中醛（R 1 CHO）烯丙基化后形成的InI充当了甲硅烷基-Prins反应的促进剂，与第二当量添加的醛（R 2 CHO）发生了反应。提出了通过这种一锅，三组分偶联方法制备环己烯基稠合的吡喃的方法，这是（±）-中心洛宾的简短形式合成。
