  • Total Synthesis of Meloscine by a [2+2]-Photocycloaddition/Ring-Expansion Route
    作者:Philipp Selig、Eberhardt Herdtweck、Thorsten Bach
    DOI:10.1002/chem.200802383
    日期:2009.3.23
    The stereogenic centers at C3 and C12 of meloscine (3) can be established in the photochemical key step 1 → 2. 1,2‐retro‐Benzilic acid rearrangement to a five‐membered ring, reductive amination, Claisen rearrangement, and ring‐closing metathesis are further key steps in the transformation of cyclobutane 2 into the target molecule 3 (14 steps, 9 % overall yield). Enantioselective access to (+)‐meloscine
    可以在光化学关键步骤1 → 2中建立甲磺胺(3)的C3和C12的立体定向中心。1,2-复古-Benzilic酸重排一个五元环,还原性胺化,Claisen重排,和闭环复分解是在环丁烷的转化进一步关键步骤2到目标分子3(14个步骤,9%总产率)。当[2 + 2]-光环加成反应是在手性模板存在下进行时,对映体可以选择性地与(+)-肌氨酸结合。
  • Synthesis studies on the Melodinus alkaloid meloscine
    作者:Ken S. Feldman、Joshua F. Antoline
    DOI:10.1016/j.tet.2012.12.032
    日期:2013.2
    The pentacyclic Melodinus alkaloid (±)-meloscine was synthesized in 19 chemical steps from 2-bromobenzaldehyde through a route featuring an allenyl azide cyclization cascade to deliver the core azabicyclo[3.3.0]octane substructure. Peripheral functionalization of this core included a Tollens-type aldol condensation to set the quaternary center at C(20) and a diastereoselective ring-closing metathesis
    五环Melodinus生物碱 (±)-meloscine 是由 2-溴苯甲醛通过 19 个化学步骤合成的,该路线以烯基叠氮化物环化级联为特征,以提供核心的氮杂双环 [3.3.0] 辛烷亚结构。该核心的外围功能化包括 Tollens 型羟醛缩合以将四元中心设置在 C(20) 和非对映选择性闭环复分解以锻造四氢吡啶环。
  • Total Synthesis of (±)-Meloscine
    作者:Yujiro Hayashi、Fuyuhiko Inagaki、Chisato Mukai
    DOI:10.1021/ol200311y
    日期:2011.4.1
    The total synthesis of (+/-)-meloscine was completed in a highly stereoselective manner starting from the known 4-(2-aminophenyl)-2,3-dihydro-N-methoxycarbonylpyrrole. The crucial step in this total synthesis involves the efficient construction of the tetracyclic framework of the target natural product by the intramolecular Pauson-Khand reaction.
  • Synthesis applications of cationic aza-Cope rearrangements. 20. Total synthesis of (.+-.)-meloscine and (.+-.)-epimeloscine

  • Allenyl Azide Cycloaddition Chemistry: Application to the Total Synthesis of (±)-Meloscine
    作者:Ken S. Feldman、Joshua F. Antoline
    DOI:10.1021/ol203463n
    日期:2012.2.3
    The pentacyclic alkaloid (+/-)-meloscine was prepared in 19 steps through a reaction sequence that features a putative azatrimethylenemethane intermediate, generated through cascade cyclization of an allenyl azide substrate, to deliver the core azabicyclo[3.3.0]octadiene substructure. Subsequent manipulation of the peripheral functionality then delivered (+/-)-meloscine.
