    Bishomoisoprenoid triazole bisphosphonates as inhibitors of geranylgeranyl diphosphate synthase
    摘要:
    Protein geranylgeranylation reactions are dependent on the availability of geranylgeranyl diphosphate (GGDP), which serves as the isoprenoid donor. Inhibition of GGDP synthase (GGDPS) is of interest from a drug development perspective as GGDPS inhibition results in impaired protein geranylgeranylation, which in multiple myeloma, disrupts monoclonal protein trafficking and induces apoptosis. We have recently reported a series of isoprenoid triazole bisphosphonates and have demonstrated that a 3:1 mixture of homogeranyl and homoneryl isomers potently, and in a synergistic manner, inhibits GGDPS. We now present the synthesis and biological evaluation of a novel series of bishomoisoprenoid triazoles which furthers our understanding of the structure-function relationship of this class. These studies demonstrate the importance of chain length and olefin stereochemistry on inhibitory activity. (C) 2017 Elsevier Ltd. All rights reserved.

  • Steric effects in intramolecular [2+2] photocycloaddition of CC double bonds to cyclohexenones.
    作者:D. Becker、N. Haddad
    DOI:10.1016/s0040-4020(01)80336-7
    日期:1993.1
    The effect of substituents on the mode of approach and the endo/exo ratio in intramolecular [2+2] photocycloaddition reactions were studied.

  • 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。

    Alkyl Grignard reagents that contain β‐hydrogen atoms were used in a stereospecific nickel‐catalyzed cross‐coupling reaction to form C(sp3)C(sp3) bonds. Aryl Grignard reagents were also utilized to synthesize 1,1‐diarylalkanes. Several compounds synthesized by this method exhibited selective inhibition of proliferation of MCF‐7 breast cancer cells.

    The cyclizations of enynes substituted at the alkyne gives products of formal [4+2] cyclization with Au(I) catalysts. 1,8-Dien-3-ynes cyclize by a 5-exo-dig pathway to form hydrindanes. 1,6-Enynes with an aryl ring at the alkyne give 2,3,9,9a-tetrahydro-1H-cyclopenta[b]naphthalenes by a 5-exo-dig cyclization followed by a Friedel-Crafts-type ring expansion. A 6-endo-dig cyclization is also observed

    secretions revealed triacylglycerols as major glandular constituents. Twelve major medium-chain fatty acids were found to be conjugated to glycerol in different combinations, resulting in complex mixtures. These acids were identified by transesterification and subsequent derivatization of natural samples, and their structures were verified by synthesis. The natural glycerides contain predominantly three of
