  • Synthesis of the B-ring of FR182877. Investigation of the reactions of 6-fumaryl 1,3,8-nonatrienes
    作者:Paul A. Clarke、Rebecca L. Davie、Simon Peace

    日期:2005.2
    under standard Diels–Alder cyclisation conditions. This rearrangement became the exclusive pathway when the reaction was performed in the presence of a Lewis acid. As expected from modeling studies, the major intramolecular Diels–Alder cyclisation product was the desired exo-trans adduct, which was required for the synthesis of FR182877. Intrigued by the rearrangements, a number of alterations were made
    据报道,分子内的Diels-Alder反应是由C5处的乙烯基取代的6-富芳基1,3,8-壬烯,以提供FR182877的B环。所需的1,3,8-壬二烯的合成可以快速,高收率地完成。在标准Diels-Alder环化条件下加热时,发现在C5处被乙烯基取代的6-Fumaryl 1,3,8-壬二烯会发生竞争性的串联σ重排/ Diels-Alder环化。当在路易斯酸的存在下进行反应时,这种重排成为排他性途径。由于模拟研究的预期,主要分子内第尔斯-阿尔德环化产物,但所需的外型-反式加合物,这是合成FR182877所必需的。重排引起了人们的兴趣,对1,3,8-壬三烯进行了许多改动。用乙酰基取代富马芳基导致1,3,8-壬三烯的反应性降低,但未观察到重排或环加成。发现C5取代基的变化对于确定Diels–Alder环化反应的π非对映选择性非常重要。
  • A Cyclic Acetal Tethered Intramolecular Diels-Alder Cycloaddition. Studies Directed toward a Total Synthesis of (±)-Fusidilactone C
    作者:Richard P. Hsung、Jiashi Wang、Sunil K. Ghosh、Yonggang Wei、John B. Feltenberger
    DOI:10.3987/com-10-s(e)93
    日期:——
    Efforts toward a synthesis of (+/-)-fusidilactone C is described here featuring a novel cyclic acetal tethered intramolecular Diels-Alder strategy. This unique and facile IMDA turned out to be highly endo-selective [endo-I and endo-II], as assessed from our mechanistic analyses. When using protic solvents or Lewis acids, the endo-I selectivity was greatly enhanced. Thus, it proved to be a real challenge to circumvent this excellent stereochemical outcome, which is undesired for the total synthesis, as an exo-II selectivity is desired. Progress was made to use the endo-II cycloadduct and to access the desired trans-2-oxadecalin motif in (+/-)-fusidilactone C.
  • De Novo Synthesis of 2-Substituted <i>syn</i>-1,3-Diols via an Iterative Asymmetric Hydration Strategy
    作者:Md. Moinuddin Ahmed、Matthew S. Mortensen、George A. O'Doherty
    DOI:10.1021/jo061200h
    日期:2006.9.1
    The enantioselective syntheses of several protected 4-substituted syn-3,5-dihydroxy carboxylic esters have been achieved from the corresponding achiral (E,E)- or (E,Z)-1,3-dienoates. The route relies upon an enantio- and regioselective Sharpless dihydroxylation and a palladium-catalyzed reduction to form gamma-substituted delta-hydroxy-1-enoates. The resulting delta-hydroxy-1-enoates are subsequently converted into benzylidene-protected 4-substituted syn-3,5-dihydroxy carboxylic esters in one step. The benzylidene-protected 3,5-dihydroxy carboxylic esters are produced in good overall yields (20-54%) and high enantiomeric excess (73- 97% ee).
