  • Asymmetric Synthesis of Quaternary Centers. Total Synthesis of (−)-Malyngolide
    作者:Barry M. Trost、Weiping Tang、Jörg L. Schulte
    DOI:10.1021/ol006599p
    日期:2000.12.1
    [structure] The deracemization of 3-nonyl-3,4-epoxybut-1-ene with Pd(0) in the presence of chiral ligands using p-methoxybenzyl alcohol as a nucleophile proceeds regio- and enantioselectively to form the monoprotected vinylglycidol in 99% ee. This chiral building block was converted in seven steps to (-)-malyngolide, an antibiotic showing significant activity against Mycobacterium smegmatis and Streptococcus
    [结构]使用对甲氧基苄醇作为亲核试剂,在手性配体存在下,用Pd(0)对3-壬基-3,4-环氧丁-1-烯进行脱环反应,在99位区域和对映体选择性形成单保护的乙烯基缩水甘油%ee。该手性结构单元在七个步骤中转化为(-)-麦芽糖内酯,这是一种对耻垢分枝杆菌和化脓性链球菌具有显着活性的抗生素。一个有趣的方面涉及通过远端羟基控制烯醇盐的质子化的非对映选择性。
  • Efficient 1,8- and 1,9-asymmetric inductions in the Grignard reaction of δ- and ɛ-keto esters of 1,1′-binaphthalen-2-ols with an oligoether tether as the 2′-substituent: application to the synthesis of (−)-malyngolide

    Efficient 1,8- and 1,9-asymmetric inductions in the Grignard reaction of podand-type δ- (3,4) and ε-keto esters (5,6) are achieved in the presence of MgBr2·OEt2 with up to 97 and 82% optical yields, respectively, by using 2′-[3-(2-methoxyethoxy)propoxy]-1,1′-binaphthalen-2-ol as the chiral auxiliary. The 1,8-asymmetric inductive Grignard reaction has been advantageously utilized in the key step of a synthesis of (−)-malyngolide.

  • Asymmetric hetero Diels–Alder route to quaternary carbon centers: synthesis of (−)-malyngolide
    作者:Arun K Ghosh、Michio Shirai
    DOI:10.1016/s0040-4039(01)01227-8
    日期:2001.9

  • Stereoselective Synthesis of Marine Antibiotic (−)-Malyngolide and Its Stereoisomers
    作者:Itsuo Ichimoto、Kozo Machiya、Mitsunori Kirihata、Hiroo Ueda
    DOI:10.1080/00021369.1990.10869988
    日期:1990.3
    A convenient synthetic method for the marine antibiotic (−)-malyngolide and its stereoisomers was accomplished from a chiral α-alkoxyketone (4), which was readily available as a chiron. Chiral quaternary carbon synthons (5a) and (5b) as the key intermediates were constructed by the chelation controlled addition of Grignard reagent to 4.The diastereomeric mixture of 5a and 5b was readily transformed into a separable mixture of lactones (7a) and (7b), each of which could be easily separated by silica-gel column chromatography. (−)-Malyngolide and its three steroisomers were obtained in optically pure form without the need for optical resolution.
    一种简便的海洋抗生素(−)-马灵果内酯及其立体异构体的合成方法得以实现,该方法从易于获得的手性α-烷氧基酮(4)作为起始物出发。通过格氏试剂对4的螯合控制加成,构建了手性四级碳合成子(5a)和(5b)作为关键中间体。5a和5b的非对映异构体混合物可方便地转化为可分离的内酯混合物(7a)和(7b),二者均可通过硅胶柱层析轻松分离。(−)-马灵果内酯及其三种立体异构体以光学纯形式获得,无需进行光学拆分。
  • AN ASYMMETRIC TOTAL SYNTHESIS OF A NEW MARINE ANTIBIOTIC-MALYNGOLIDE

    DOI:10.1246/cl.1980.1223
    日期:1980.10.5
    (−)-Malyngolide was synthesized from (S)-2-hydroxy-2-nonyl-6-heptenal, prepared in high optical yield by an asymmetric synthesis using (S)-2-(anilinomethyl)pyrrolidine as a chiral auxiliary.
