    菲吲哚里西啶生物碱 (+/-)-antofine、(+/-)-deoxypergularinine 及其脱氢同源物的全合成及其细胞毒活性的评估。
    摘要:
    由于其有限的天然丰度和显着的生化效应,我们从相应的合成生物碱 (+/-)-安托芬 (1a)、(+/-)-脱氧泛碱 (1b) 及其脱氢同源物 (2 和 3) 开始菲-9-甲醛。我们还评估了它们的体外细胞毒活性。化合物 1a 和 1b 显示出对各种人类肿瘤细胞系的显着效力,包括一种耐药变体,EC(50) 值范围从 0.16 到 16ng/mL。还确定了这些生物碱及其一些合成中间体的构效关系。菲和吲哚里西啶这两个主要部分之间的非平面结构在菲并吲哚里西啶的细胞毒活性中起着至关重要的作用。增加吲哚里西啶部分的平面度和刚性显着降低了效力。

    Synthesis of Tylocrebrine and Related Phenanthroindolizidines by VOF3-Mediated Oxidative Aryl-Alkene Coupling
    摘要:
    A highly convergent strategy to prepare phenanthroindolizidines is reported involving three consecutive C-C coupling reactions. This sequence features a novel VOF3-mediated aryl-alkene coupling in the final step, which enables regioselective preparation of C5-substituted phenanthroindolizidines for the first time. This strategy has been applied to the synthesis of eight natural and unnatural members in this class to investigate the scope of this chemistry and to explore structure-activity relationships.

  • Directed ortho metallation of tertiary aromatic amides
    作者:M. Iwao、K.K. Mahalanabis、M. Watanabe、S.O. De Silva、V. Snieckus
    DOI:10.1016/s0040-4020(01)91913-1
    日期:1983.1
    cryptopleurine (8) and antofine (9) via directed ortho metallation of the common phenanthrene (1) are described (Scheme 2). The utility of this strategy as a new N-heteroring annelation method (Scheme 1) is illustrated by the preparation of other aromatic ring-fused quinolizidine (12,15) and indolizidine (18,21) systems. A Mg for Li transmetallation, crucial for the synthesis of 13 and of potential broader
    描述了通过普通菲(1)的定向邻位金属化反应合成菲咯啉-喹唑烷和-吲哚唑烷生物碱,隐藻碱(8)和antofine(9)(方案2)。此策略为新的N-杂环成环方法(所述的实用方案1)由其他芳族环稠合的喹嗪啶(制备图示12,15)和吲哚里(18,21)的系统。报道了一种用于Li过渡金属化的Mg,它对于13的合成至关重要,并且在定向金属化化学中具有潜在的更广泛的意义。
  • Modular Syntheses of Phenanthroindolizidine Natural Products
    作者:Young-In Jo、Martin D. Burke、Cheol-Hong Cheon
    DOI:10.1021/acs.orglett.9b01397
    日期:2019.6.7
    A highly concise strategy for the total synthesis of phenanthroindolizidines was developed. The one-pot iterative Suzuki–Miyaura reaction of aryl boronic acids with ortho-bromoaryl N-methyliminodiacetate (MIDA) boronate followed by a second Suzuki–Miyaura reaction with a suitable pyridyl bromide provided ortho-aza-terphenyls. Subsequent saturation of the triple bond, treatment with mesyl chloride,
    提出了一种高度简洁的菲咯啉吲哚全合成策略。芳基硼酸与邻-溴芳基N-甲基亚氨基二乙酸酯(MIDA)硼酸酯的一锅迭代Suzuki-Miyaura反应,然后与合适的吡啶溴化物提供的邻-氮杂-三联苯进行第二次Suzuki-Miyaura反应。随后使三键饱和,用甲磺酰氯处理,并还原所得的二氢吲哚并鎓环,得到六氢吲哚并酮。最终的钒催化氧化电环化仅在三个色谱柱分离操作中即可提供所需的生物碱。
  • Cyano Group Removal from Cyano-Promoted Aza-Diels–Alder Adducts: Synthesis and Structure–Activity Relationship of Phenanthroindolizidines and Phenanthroquinolizidines
    作者:Chi-Fen Chang、Chien-Fu Li、Chia-Chen Tsai、Ta-Hsien Chuang
    DOI:10.1021/acs.orglett.5b03395
    日期:2016.2.19
    Phenanthroindolizidines and phenanthroquinolizidines were concisely synthesized by the reductive decyanization of cyano-promoted intramolecular aza-Diels–Alder cycloadducts followed by aryl–aryl coupling. Cyano groups were removed from α-aminoacrylonitriles via treatment with sodium borohydride in 2-propanol in almost quantitative yields; a possible mechanism was proposed and examined using D-labeling experiments

  • Total Synthesis of Antofine Using the Net [5+5]-Cycloaddition of γ,δ-Unsaturated Carbene Complexes and 2-Alkynylphenyl Ketones as a Key Step
    作者:Alejandro Camacho-Davila、James W. Herndon
    DOI:10.1021/jo061053n
    日期:2006.8.1
    A compound containing all of the carbons of the anticancer agent antofine was produced in a single step from the coupling of a γ,δ-unsaturated carbene complex with a 2-alkynylphenyl ketone derivative. Subsequent conversion to antofine was effected in three steps.

  • Total Synthesis of Phenanthroindolizidine Alkaloids by Combining Iodoaminocyclization with Free Radical Cyclization
    作者:Gong-Qing Liu、Marcel Reimann、Till Opatz
    DOI:10.1021/acs.joc.6b01161
    日期:2016.7.15
    A concise and modular synthesis of phenanthroindolizidine alkaloids was achieved by combining iodoaminocylization with a free radical cyclization approach. The route described allowed the preparation of (±)-tylophorine, (±)-antofine, and (±)-deoxypergularinine in six steps. When commercially available l-prolinol was used as a chiral building block, (S)-(+)-tylophorine was also synthesized in 49% yield
    通过结合碘氨基环化和自由基环化方法,实现了菲咯啉吲哚啶生物碱的简明和模块化合成。所描述的途径允许在六个步骤中制备(±)-酪氨酸,(±)-antofine和(±)-脱氧pergularinine。当将市售的1-脯氨醇用作手性结构单元时,在五个线性步骤中也以49%的产率和> 99%的ee合成了(S)-(+)-酪氨酸。
