  • Asymmetric Synthesis of (+)- and (–)-Streptenol A
    作者:Dieter Enders、Thomas Hundertmark
    DOI:10.1002/(sici)1099-0690(199904)1999:4<751::aid-ejoc751>3.0.co;2-r
    日期:1999.4
    The asymmetric synthesis of (+)-streptenol A was carried out in ten steps and with high enantioselectivity (ee ≥ 96%). The key steps are the α-alkylation of 2,2-dimethyl-1,3-dioxan-5-one RAMP hydrazone A (1), subsequent deoxygenation and elaboration of the side chain via aldehyde B to furnish (+)-streptenol A in 23% overall yield. In analogy, the enantiomer ()-streptenol A was synthesized using the
    (+)-链烯醇 A 的不对称合成分十步进行,具有高对映选择性(ee ≥ 96%)。关键步骤是 2,2-二甲基-1,3-二恶烷-5-one RAMP 腙 A (1) 的 α-烷基化,随后通过醛 B 脱氧和加工侧链以提供 (+)-链烯醇 A总产率为 23%。类似地,使用相应的 SAMP 腙以 18% 的总产率合成对映异构体 (-)-链烯醇 A。
  • Stereochemical Determination of Roflamycoin: 13C Acetonide Analysis and Synthetic Correlation
    作者:Scott D. Rychnovsky、George Griesgraber、Rolf Schlegel
    DOI:10.1021/ja00106a024
    日期:1995.1
    The relative configuration of natural roflamycoin (1) was determined by C-13 acetonide analysis, combined with other supporting spectroscopic data. A previous proposal for the configuration of roflamycoin was shown to be incorrect. The absolute configuration was determined by the advanced Mosher's method. Our proposed structure of natural roflamycoin was confirmed by the synthesis of a degradation fragment that incorporates all of the 11 independent stereogenic centers of roflamycoin. The complete structure of roflamycoin is illustrated in Figure 1.
  • Synthesis of (−)-Streptenol A, (±)-Streptenol B, C and D
    作者:Siegfried Blechert、Heribert Dollt
    DOI:10.1002/jlac.199619961228
    日期:1996.12
    3-dioxan-4-yl)acetaldehyde (3) was used for the preparation of streptenol A and B (Scheme 1) via a Grignard reaction with 1-bromopent-3-ene. Hereby optically pure (4′R)-3 gave the antipode of Streptenol A. Reaction with lithiated 1-pentyne opened access to streptenol C and D. To obtain the dienone structure of streptenol C and D, a palladium-catalyzed alkynone isomerization was induced. Kinetic differences
    通过与1-溴戊-3-烯的格氏反应,使用2-(2,2-二甲基-1,3-二恶烷-4-基)乙醛(3)制备链烯醇A和B(方案1)。特此光学纯(4' - [R )- 3,得到Streptenol A.反应的对映体与锂化的1-戊炔打开访问streptenol C和D为获得streptenol C和d的二烯酮结构,钯催化的炔酮异构化诱导。1,3-丙酮化物保护的1,3,5-三醇系统在酸介导的裂解中的动力学差异导致了天然产物的立体选择性。所以只有(3 S *,5 R *)链烯醇B的丙酮化物在温和的水解条件下反应,并在缩醛化后首先提供具有相对相对立体化学的3,5-保护的链烯醇B,最后是(3 S *,5 R *)-链烯醇B.
  • Synthesis and absolute stereochemistry of the acyl moiety of quillajasaponins
    作者:Xiangming Zhu、Biao Yu、Yongzheng Hui、Ryuichi Higuchi、Takanori Kusano、Tomofumi Miyamoto
    DOI:10.1016/s0040-4039(99)02124-3
    日期:2000.1
    The acyl moiety of the quillajasaponins, one of the most important immunological adjuvants, was determined to be 3-(S), 5-(S)-dihydroxy-6-(S)-methyl-octanoic acid by enantioselective synthesis. (C) 2000 Elsevier Science Ltd. All rights reserved.
