    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.

  • Intramolecular [2+2] Photocycloaddition of Cyclic Enones: Selectivity Control by Lewis Acids and Mechanistic Implications
    作者:Saner Poplata、Andreas Bauer、Golo Storch、Thorsten Bach

    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。

    The [2 + 2] intramolecular photocycloaddition of E and Z olefins to a cyclohexenone has been investigated; it is concluded that the bond to C(3) in the cyclohexenone is formed first to give the diradical intermediates (7a) and (7b).
