    虽然 3,3-二甲基双环 [3.3.1]nonan-2-one (5) 在强碱性条件 (t-BuO−/t-BuOH/185 °C) 下稳定,但其异构体 3,3-二甲基双环 [3.2 .2]nonan-2-one (6),慢慢转化为 5。同样,3,3-二甲基双环-[3.2.2]non-6-en-2-one (8b) 重排为 [3.3.1 ] 异构体,但后者不稳定。3,3-二甲基双环[3.3.1]non-6-en-2-one (7) 的实验表明,它被转化为五种化合物,其中没有一种是 8b。主要产物 8,8-二甲基双环 [4.3.0]non-1(6),-en-7-one (11) 产生于 β-烯醇重排。Enone 11 缓慢还原为顺式和反式 8,8-二甲基双环 [4.3.0]nonan-7-one,大概是通过单电子转移。单独使用 11 的实验表明 7 → 11 的 β-烯醇重排是单向的。Haller-Bauer

    Metal-Catalyzed Chemoselective Cycloisomerization of cis-2,4-Dien-1-als to 3-Cyclopentenones and 4-Alkylidene-3,4-dihydro-2H-pyrans
    摘要:
    [GRAPHICS]PtCl2 (5 mol %) catalyst effected cycloisomerization of cis-2,4-dien-1-al (1) to 3-cyclopentenone (3) efficiently in hot toluene. In the presence of p-TSA, this PtCl2 catalysis gave 2-cyclopentenone (5) exclusively because of the secondary isomerization reaction. Although the 1-2 equilibrium state greatly favors aldehyde (1), PdCl2(PhCN)(2)(5 mol %) catalyzed cycloisomerization of aldehyde (1) to 4,6,7,8-tetrahydro-3H-isochromene (4) smoothly in hot toluene. A plausible mechanism is proposed on the basis of reaction observation and isotope-labeled experiment.

  • Gold-Catalyzed Deoxygenated Cyclization of <i>cis</i>-2,4-Dien-1-als with Regioselective Addition of Two Nucleophiles. One-Pot Synthesis of Highly Functionalized Cyclopentene Framework

    We report a new gold-catalyzed deoxygenated cyclization of cis-2,4-dien-1-als with external nucleophiles at ambient temperatures, which leads to a 1,4-double nucleophilic addition to the newly formed cyclopentene ring. The use of this cyclization is reflected not only by its compatibility with a wide scope of nucleophiles, but also by a facile construction of complex frameworks in diversified approaches

    annulation products reveals evidence for the participation of Nazarov cyclization. This deoxygenative cyclization is extensible to a tandem intramolecular cyclization/nucleophilic addition cascade, giving polycyclic carbo- or oxacyclic compounds with controlled stereochemistry. This new gold catalysis is applied to a short synthesis of natural compounds of the brazilane family, including brazilane, O-trimethyl-

    While 3,3-dimethylbicyclo[3.3.1]nonan-2-one (5) is stable under strongly basic conditions (t-BuO−/t-BuOH/185 °C), its isomer, 3,3-dimethylbicyclo[3.2.2]nonan-2-one (6), is slowly transformed to 5. Similarly, 3,3-dimethylbicyclo-[3.2.2]non-6-en-2-one (8b) rearranges to a [3.3.1] isomer but the latter is not stable. Experiments with 3,3-dimethylbicyclo[3.3.1]non-6-en-2-one (7) revealed that it is converted
