    Stereocontrolled Syntheses of C-Aryl Taxanes By Intramolecular Heck Olefination. Novel Instances of Diastereofacial Guidance By Proximal Coordination
    摘要:
    Stereospecific syntheses of baccatin III constructs bearing an aromatic C-ring (2a and 2b) have been demonstrated. A key step involves the use of an intramolecular Heck olefination reaction to form the C-10-C-11 bond (see transformations 15 --> 16 and 27 --> 28). Novel stereospecific reactions en route to 2a and 2b were also discovered (see 8 --> 10, 8 --> 23, 13 --> 14, and 25 --> 26).

  • Synthesis of a diterpene taxoid skeleton, bicyclo[9.3.1]pentadecatriene
    作者:Satoshi Shibuya、Minoru Isobe
    DOI:10.1016/s0040-4020(98)00334-2
    日期:1998.6
    1]pentadecatriene skeleton was investigated by employing cyclization reactions using two key precursors bearing acetylene cobalt complex. Cyclization for the synthesis of strained twelve-membered ring was achieved via Nicholas type reaction in reasonable yield. Reductive decomplexation of the dicobalt hexacarbonyl moiety of the cyclization product was achieved with n-Bu3SnH in the presence of a catalytic amount
    通过使用两个带有乙炔配合物的关键前体的环化反应,研究了双环[9.3.1]十五碳三烯骨架的合成。通过Nicholas型反应以合理的产率实现了用于合成应变十二元环的环化。在1,4-环己二烯溶剂中催化量的NBS存在下,用n -Bu 3 SnH对环化产物的二六羰基部分进行还原分解。
  • Development of silicon-tethered anionic reaction and its application to the synthesis of chiral A-ring moieties of Taxol™

    DOI:10.1016/j.tetlet.2004.09.143
    日期:2004.11
    Silicon-tethered intramolecular nucleophilic additions of a hydroxymethyl unit to ketones in β-hydroxyketones have been developed. The product obtained by this protocol was successfully converted to chiral A-ring moieties of Taxol™. Also developed was a promising silicon-tethered intramolecular α-alkylation reaction of the cyclic hydroxyketone.
    已经开发了羟基甲基单元的拴分子内亲核加成物到β-羟基酮中的酮上。通过该方案获得的产物已成功转化为Taxol™的手性A环部分。还开发了有希望的环状羟基酮的系分子内α-烷基化反应。
  • A short and enantioselective preparation of taxol A-ring fragment
    作者:Sho Hirai、Naoko Urushizako、Masayuki Miyano、Tomohiro Fujii、Masahisa Nakada
    DOI:10.1016/j.tetlet.2013.01.115
    日期:2013.4
    preparations of the taxol A-ring fragment are described: one via organocatalyzed α-aminoxylation and the other via Sharpless asymmetric dihydroxylation (SAD). The former approach affords the A-ring fragment in 10 steps, and the latter approach involves eight steps to afford the new A-ring fragment in 91% ee, which is made enantiomerically pure through recrystallization. The new A-ring fragment bearing a bromoalkene
    描述了紫杉醇A环片段的两种简短制备方法:一种是通过有机催化的α-氧基化反应,另一种是通过Sharpless不对称二羟基化反应(SAD)。前一种方法分10步提供A环片段,后一种方法包括8个步骤以91%ee提供新的A环片段,通过重结晶使对映体纯。证实带有代烯烃的新的A-环片段可用于通过催化的分子内烯基化形成紫杉醇模型化合物的碳环八元环。新的A环片段的制备将有助于紫杉醇以及其他天然产物的全合成
