    摘要:
    从鱼类病原体海分枝杆菌中分离出的分枝杆菌内酯 F 的拟议结构 9 是由核心醇 7 和不饱和酸 6 合成的。合成 9 的 1H NMR 光谱与报道的天然分枝杆菌 F 的 1H NMR 光谱匹配,从而证明了mycolactone F 的结构为 9 或其远程非对映异构体 10。为了开发一种分析方法来区分它们,从 7 和 6 的对映体合成 10。使用合成材料,开发了手性 HPLC 方法来区分它们10 来自 9。然后将这种分析方法应用于天然产物,从而确定支链内酯 F 的完整结构令人惊讶的是 10,而不是 9。有趣的是,来自鱼类病原体 M 的支链内酯 F 的不饱和脂肪酸的绝对构型.marinum 对应于存在于来自人类病原体溃疡分枝杆菌的天然分枝杆菌内酯 A/B 和 C 中的对映体。

  • Further studies on silatropic carbonyl ene cyclisations: β-crotyl(diphenyl)silyloxy aldehyde substrates; synthesis of 2-deoxy-2-C-phenylhexoses

    carbonyl ene cyclisations of beta-(allylsilyloxy)- and beta-(crotylsilyloxy)butyraldehydes are shown to proceed with high stereoselectivity but at a much reduced rate in comparison to the cyclisation of analogous alpha-substrates. In the second section, olefin cross-metathesis is explored as a route to substituted alpha-(allylsilyloxy)aldehydes and the method applied to the synthesis of diastereomeric

    Enantioselective microbial hydrolysis of C1 and C2 dissymmetrical cyclic carbonates with disubstitution (methyl and another groups) has been developed. Pseudomonas diminuta (FU0090), a bacterium, efficiently catalyzes the hydrolysis of five-membered cyclic carbonates. While the trans-substrates are hydrolyzed with low enantioselectivities and/or reactivities, the microbe hydrolyzes the cis-substrates

    The iridium‐catalyzed, protecting group‐free synthesis of 4‐hydroxy‐2,6‐cis‐ or trans‐pyrans through successive nucleophilic and electrophilic allylations of chiral 1,3‐diols occurs with complete levels of catalystdirected diastereoselectivity in the absence of protecting groups, premetallated reagents, or discrete alcohol‐to‐aldehyde redox reactions.

  • Addition of Allylindium Reagents to Aldehydes Substituted at C<sub>α</sub> or C<sub>β</sub> with Heteroatomic Functional Groups. Analysis of the Modulation in Diastereoselectivity Attainable in Aqueous, Organic, and Mixed Solvent Systems
    作者:Leo A. Paquette、Thomas M. Mitzel
    DOI:10.1021/ja953682c
    日期:1996.1.1
    The stereochemical course of indium-promoted allylations to alpha- and beta-oxy aldehydes has been investigated in solvents ranging from anhydrous THF to pure H2O. The free hydroxyl derivatives react with excellent diastereofacial control to give significantly heightened levels of syn-1,2-diols and anti-1,3-diols. Relative reactivities were determined in the alpha-series, and the hydroxy aldehyde proved to be the most reactive substrate. This reactivity ordering suggests that the selectivity stems from chelated intermediates. The rate acceleration observed in water can be heightened by initial acidification. Indeed, the indium-promoted allylation reaction mixtures become increasingly acidic on their own. Preliminary attention has been accorded to salt effects, and tetraethylammonium bromide was found to exhibit a positive synergistic effect on product distribution. Finally, mechanistic considerations are presented in order to allow for assessment of the status of these unprecedented developments at this stage of advancement of the field.
  • Chelation control associated with organometallic addition reactions in water. The high stereoselectivity offered by α- and β-hydroxyl substituents obviates the need for protecting groups
    作者:L Paquette
    DOI:10.1016/00404-0399(50)1439o-
    日期:1995.9.18
    High stereoselectivities have been observed for indium-promoted allylations of alpha- and beta-hydroxy aldehydes in aqueous media, with strong implication that chelate control can continue to operate in water.
