  • Synthetic Studies on Halichondrin B, an Antitumor Polyether Macrolide Isolated from a Marine Sponge. 9. Synthesis of the C16-C36 Unit via Stereoselective Construction of the D and E Rings.
    作者:Kiyoshi HORITA、Masaaki NAGASAWA、Youji SAKURAI、Osamu YONEMITSU
    DOI:10.1248/cpb.46.1199

    The C16-C36 unit of halichondrin B was stereoselectively synthesized via the aldol condensation of two C16-C26 esters with the previously synthesized C27-C36 aldehyde followed by E ring construction. The C16-C26 esters were prepared starting from (2S)-3-hydroxy-2-methylpropionic acid and L-tartaric acid via construction of the D ring by iodoetherification.
    通过两个C16-C26酯与之前合成的C27-C36醛的醛醇缩合反应,继而构建E环,立体选择性地合成了halichondrin B的C16-C36单元。C16-C26酯是以(2S)-3-羟基-2-甲基丙酸和L-酒石酸为起始原料,通过碘醚化构建D环制备而成。
  • Synthetic Studies of Halichondrin B, an Antitumor Polyether Macrolide Isolated from a Marine Sponge. 7. Synthesis of Two C27-C36 Units via Construction of the F Ring and Completely Stereoselective C-Glycosylation Using Mixed Lewis Acids.
    作者:Kiyoshi HORITA、Youji SAKURAI、Masaaki NAGASAWA、Osamu YONEMITSU
    DOI:10.1248/cpb.45.1558
    日期:——
    Two C27-C36 units of halichondrin B were synthesized starting from a C31-C34 alcohol, which was easily available from dimethyl L-tartrate, via construction of the F ring, methylation at the C31 position and C-glycosylation. These crucial reactions proceeded completely stereoselectively, and in particular the stereoselective C-glycosylation with allyltrimethylsilane took place only in the presence of both of two Lewis acids, boron trifluoride etherate and trimethylsilyl triflate.
    从容易获得的二甲基L-酒石酸盐出发,合成了两个C27-C36单元的海绵素B,这一过程通过构建F环、在C31位进行甲基化和C-糖苷化实现。这些关键反应完全具有立体选择性,尤其是与烯丙基三甲基硅烷的立体选择性C-糖苷化仅在两种路易斯酸——三氟化硼醚合物和三甲基硅基三氟甲磺酸盐的共同存在下进行。
  • Synthetic studies of halichondrin B, an antitumor polyether macrolide isolated from a marine sponge. 8. Synthesis of the lactone part (C1C36) via horner-emmons coupling between C1C15 and C16C36 fragments and Yamaguchi lactonization

    The lactone part (2) of halichondrin B (1) was synthesized by Yamaguchi macrolactonization of the seco-acid (3), which was synthesized via coupling of C1C15(4) with C16C36 (5), prepared through stereoselective construction of the E ring starting from C16C26 (7) and C27C36 (8).
    通过山口宏观内酯化癸二酸(3)合成了葫芦素B(1)的内酯部分(2),其通过C1 constructionC15(4)与C16C36(5)的偶联合成,并通过立体选择性结构制备从C16C26(7)和C27C36(8)开始的E环。
