  • Asymmetric total synthesis of octalactin B using a new and rapid lactonization
    作者:Isamu Shiina、Hiromi Oshiumi、Minako Hashizume、Yu-suke Yamai、Ryoutarou Ibuka
    DOI:10.1016/j.tetlet.2003.10.213
    日期:2004.1
    A method for the synthesis of octalactin B is established via a new and quite effective mixed-anhydride lactonization for the synthesis of an eight-membered ring moiety using 2-methyl-6-nitrobenzoic anhydride with DMAP. Both an optically active linear precursor of the lactone and a side chain of octalactins are prepared by the enantioselective aldol reaction of ketene silyl acetals with aldehydes.
    通过新的且非常有效的混合酸酐内酯化方法建立了八聚肌动蛋白B的合成方法,该方法使用2-甲基-6-硝基苯甲酸酐和DMAP合成八元环部分。内酯的旋光性线性前体和八聚肌动蛋白的侧链均通过烯酮甲硅烷基缩醛与醛的对映选择性醛醇缩合反应制备。
  • Synthesis of octalactin lactone and side chain
    作者:Merritt B. Andrus、Ankush B. Argade
    DOI:10.1016/0040-4039(96)01014-3
    日期:1996.7
    synthesized in a direct, and efficient manner. Lactone 1 was made using a substrate controlled lactonization reaction using the carbodiimide EDCI and two crotylborane additions were used to access the precursor hydroxyacid. The importance of proper substitution in the hydroxyacid tether is noted for successful medium-ring lactonization. Synthesis of the side chain vinyl iodide 2 employed an asymmetric allenylboronate
    已经以直接,有效的方式合成了(+)-八-半乳糖苷A(一种有效的新的细胞毒性天然产物)的两个关键中间体。内酯1是通过使用碳二亚胺EDCI进行底物控制的内酯化反应制得的,并使用了两次巴豆基硼烷的加入来获得前体羟基酸。注意到在羟基酸系链中正确取代的重要性对于成功的中环内酯化是重要的。侧链乙烯基碘化物2的合成采用不对称的烯丙基硼酸酯加成。
  • Total Synthesis of Octalactin A and B
    作者:Keith R. Buszek、Nagaaki Sato、Youngmee Jeong
    DOI:10.1021/ja00091a082
    日期:1994.6
  • Synthetic efforts toward the synthesis of octalactins
    作者:Minh-Thu Dinh、Samir Bouzbouz、Jean-Louis Péglion、Janine Cossy
    DOI:10.1016/j.tet.2008.04.026
    日期:2008.6
    Octalactin B was synthesized from the commercially available methyl-3-butenoate and isobutyraldehyde, using enantioselective allyl- and crotyltitanations to control the stereogenic centers at C3, C4, C7, C8, and C13. Moreover, the two other key-step reactions are a cross-metathesis reaction and a lactonization, using the effective anhydride MNBA, to build up the eight-membered ring lactone. (C) 2008 Elsevier Ltd.

  • Enantioselective Total Synthesis of Octalactin A Using Asymmetric Aldol Reactions and a Rapid Lactonization To Form a Medium-Sized Ring
    作者:Isamu Shiina、Minako Hashizume、Yu-suke Yamai、Hiromi Oshiumi、Takahisa Shimazaki、Yu-ji Takasuna、Ryoutarou Ibuka
    DOI:10.1002/chem.200500417
    日期:2005.11.4
    Octalactin A, an antitumor agent containing an eight-membered lactone moiety, has been stereoselectively prepared by means of enantioselective aldol reactions of selected silyl enolates with achiral aldehydes, promoted by a chiral Sn(II) complex. The medium-sized lactone part was effectively constructed by way of a new and rapid mixed-anhydride lactonization using 2-methyl-6-nitrobenzoic anhydride
    已通过手性Sn(II)配合物促进选定的甲硅烷基烯醇化物与非手性醛的对映选择性醛醇缩合反应立体选择性地制备了八元内酯A,一种含有八元内酯部分的抗肿瘤剂。通过使用催化量为4-(二甲基氨基)吡啶(DMAP)或4-(二甲基二甲基氨基)吡啶-1-氧化物(DMAPO)。仅使用5 mol%的DMAP或2 mol%的DMAPO可以迅速促进八聚actin的中等大小环的形成,这证明了新内酯化方案的显着效率。
