  • A Chemoenzymatic Total Synthesis of the Undecenolide ( - )-Cladospolide C
    作者:Martin G. Banwell、David T. J. Loong、Anthony C. Willis
    DOI:10.1071/ch05074
    日期:——

    The (−)-enantiomer, ent-3, of the natural product (+)-cladospolide C (3) has been prepared for the first time using the monochiral cis-1,2-dihydrocatechol 5 as starting material. Key steps include coupling of the derived acid 6 with the enzymatically generated (S)-(+)-4-penten-2-ol (7) and ring-closing metathesis (RCM) of the resultant doubly unsaturated ester 8 to give lactone 9. The structure of this last compound has been confirmed by single-crystal X-ray analysis. This work has established that the absolute configuration of (+)-cladospolide C has been correctly assigned and is as illustrated in structure 3.

    以单手性顺式-1,2-二氢邻苯二酚 5 为起始原料,首次制备了天然产物 (+)-cladospolide C (3) 的 (-)- 对映异构体 ent-3。关键步骤包括将衍生的酸 6 与酶法生成的 (S)-(+)-4- 戊烯-2-醇 (7) 进行偶联,并对生成的双不饱和酯 8 进行闭环偏析 (RCM),从而得到内酯 9。最后一种化合物的结构已通过单晶 X 射线分析得到证实。这项工作确定了 (+)-cladospolide C 的绝对构型,如结构 3 所示。
  • First synthesis and determination of the absolute stereochemistry of iso-cladospolide-B and cladospolides-B and C
    作者:G.V.M. Sharma、K. Laxmi Reddy、J. Janardhan Reddy
    DOI:10.1016/j.tetlet.2006.07.044
    日期:2006.9
    The syntheses of iso-cladospolide-B, cladospolide-B and cladospolide-C are reported with 4S,5S,11S-configuration. Of the three stereogenic centres, the C-4/C-5 vic-diol was created by Evans aldol condensation, while the C-11 stereocentre was created by Jacobsen's method. The synthesis of cladospolides 1-3 defined the absolute stereochemistry of these natural products. (c) 2006 Elsevier Ltd. All rights reserved.
  • Enantioselective total synthesis of iso-cladospolide B, cladospolide C and cladospolide B from tartaric acid
    作者:Kavirayani R. Prasad、Vasudeva Rao Gandi
    DOI:10.1016/j.tetasy.2011.02.018
    日期:2011.3
    The enantioselective synthesis of the natural products cladospolide B, cladospolide C, and iso-cladospolide B has been accomplished from tartaric acid. Key reactions in the synthetic sequence include the elaboration of a gamma-hydroxy amide derived from tartaric acid via alkene cross metathesis, Yamaguchi lactonization, and ring closing metathesis.

  • Stereoselective Total Synthesis of (-)-Isocladospolide B and Cladospolide B and C
    作者:J. Yadav、S. Mandal
    DOI:10.1055/s-0031-1289868
    日期:2011.12
    The enantioselective synthesis of bioactive butenolides isocladospolide B, cladospolide B, and cladospolide-C has been achieved from (S)-propylene oxide. Of the three stereogenic centers, the C-4/C-5 vic-diol was obtained using diastereo- and enantio­selective Brown hydroxycrotylation, while the C-11 stereocenter was created by Jacobsen hydrolytic kinetic resolution.
    已通过(S)-丙烯氧化物实现了生物活性丁烯内酯异克拉多斯波利德B、克拉多斯波利德B和克拉多斯波利德C的对映选择性合成。在三个立体中心中,C-4/C-5邻二醇是通过二对映体和对映选择性的布朗羟基克罗提化法获得的,而C-11立体中心则是通过雅各布森水解动力学分辨法构建的。
