    Regiochemistry and stereochemistry of intramolecular [2+2] photocycloaddition of carbon-carbon double bonds to cyclohexenones
    摘要:
    The intramolecular [2 + 2] photocycloaddition mechanism of alkenes tethered by a three-methylene chain to cyclohexenones has been studied. It was found that the reversion from a 1,4-diradical intermediate to starting material is slow relative to the rate of photoadduct formation. Only ''straight'' closure was observed in the systems studied. For compounds 1-3 and 5, the assumption that the first bond is formed between the beta-carbon of the enone and C-4' leading to a 1,4-diradical is supported. For the formation of compounds 6-11, possible mechanisms are discussed.

  • Synthesis of bicyclic lactones via I2-mediated intramolecular tandem C–C/C–O bond formation

    The iodine/DMAP-mediated intramolecular tandem C–C/C–O bond forming reaction of malonate bearing alkene moiety proceeded to give bicyclic lactones with good diastereoselectivity in good yield. The mechanistic investigation was also discussed on the basis of various control experimental results.

  • Intramolecular [2+2] Photocycloaddition of Cyclic Enones: Selectivity Control by Lewis Acids and Mechanistic Implications

    that attractive dispersion forces may be responsible for a change of the binding mode. The catalytic [2+2] photocycloaddition was shown to proceed on the triplet hypersurface with a quantum yield of 0.05. The positive effect of Lewis acids on the outcome of a given intramolecular [2+2] photocycloaddition was illustrated by optimizing the key step in a concise total synthesis of the sesquiterpene (±)‐italicene
    在存在λ = 366 nm的条件下进行辐照时,以对映选择性的方式进行3-烯基-2-环烯酮的分子内[2 + 2]光环加成反应(九个代表性实例,产率为54-86%,ee为76-96%ee)。 AlBr 3活化的恶唑硼烷作为路易斯酸。对脯氨酸衍生的恶唑硼烷的广泛筛选表明,对映体的分化很大程度上取决于杂环3位上芳基的性质。路易斯酸-底物复合物的DFT计算表明,有吸引力的分散力可能是改变结合模式的原因。催化的[2 + 2]光环加成反应在三重态超表面上进行,量子产率为0.05。通过优化倍半萜烯(±)-斜体的简明全合成中的关键步骤,可以说明路易斯酸对给定的分子内[2 + 2]光环加成反应的积极作用。

    A screen of catalysts revealed that more electron-rich phosphine ligands resulted in higher yields of the desired product, with selenophosphoramides giving the optimal results. A broad range of substrates and functional groups were tolerated and yields were generally good to excellent. For (E)-1,2-disubstituted olefins, diastereoselectivities were always high, giving exclusively anti products. The conditions
    提出了一种新的硒代磷酰胺催化的端基和反式1,2-二取代烯烃的加氨反应。该转化成功的关键是引入氟化物清除剂三甲基甲硅烷基三氟甲磺酸盐(TMSOTf),以防止竞争性的同化途径,就像在硒上使用磷酰胺配体来促进所需的取代反应一样。催化剂的筛选表明,更多的富含电子的膦配体导致所需产物的更高产率,硒代磷酰胺给出了最佳结果。可以耐受各种各样的底物和官能团,并且收率通常良好至优异。对于(E)-1,2-二取代的烯烃,非对映选择性始终很高,仅产生抗产物。
