  • Formal Total Synthesis of Okadaic Acid via Regiocontrolled Gold(I)-Catalyzed Spiroketalizations
    作者:Chao Fang、Yucheng Pang、Craig J. Forsyth
    DOI:10.1021/ol101833h
    日期:2010.10.15
    Both C19 and C34 spiroketal domains of okadaic acid were assembled using gold(I) chloride catalyzed spiroketalizations, and the two resulting fragments were coupled to give the C15−C38 fragment of okadaic acid, a known intermediate for the total synthesis of this important natural product.
    冈田酸的C19和C34螺环域都使用氯化金(I)催化的螺环化进行组装,然后将得到的两个片段偶联,得到冈田酸的C15-C38片段,这是一种重要的天然产物的总合成方法,是已知的中间体。
  • Total Synthesis of Discodermolide: Optimization of the Effective Synthetic Route
    作者:Elsa de Lemos、François-Hugues Porée、Arnaud Bourin、Julien Barbion、Evangelos Agouridas、Marie-Isabelle Lannou、Alain Commerçon、Jean-François Betzer、Ange Pancrazi、Janick Ardisson

    日期:2008.12.8
    An efficient and modulable total synthesis of discodermolide (DDM), a unique marine anticancer polyketide is described including related alternative synthetic approaches. Particularly notable is the repeated application of a crotyltitanation reaction to yield homoallylic (Z)-O-ene-carbamate alcohols with excellent selectivity. Advantage was taken of this reaction not only for the stereocontrolled building
    一种高效,可调节的二甲蝶呤(DDM)的合成方法,一种独特的海洋抗癌聚酮化合物,包括相关的替代合成方法。尤其值得注意的是,重复进行crotyltitanate反应,以具有优异的选择性产生均烯丙基(Z)-O-烯-氨基甲酸酯醇。利用该反应不仅用于DDM的顺-反甲基-羟基-甲基三单元组的立体控制结构,而且还用于末端(Z)-二烯的直接结构。还特别感兴趣的是通过高度选择性的致各向异性重排来安装C13 = C14(Z)-双键。在两个连续阶段中制备中间C8-C14片段并将其与C1-C7部分偶联是一个真正的挑战,需要仔细优化。探索了几种合成路线以允许高和可靠的产量。由于这种方法的灵活性和鲁棒性,它可以实现DDM的系统结构变化,因此可以开发和探索新颖的discodermolide结构类似物。
  • Efficient Synthesis of Okadaic Acid. 1. Convergent Assembly of the C15−C38 Domain
    作者:Rebecca A. Urbanek、Steven F. Sabes、Craig J. Forsyth
    DOI:10.1021/ja973287h
    日期:1998.3.1
    A convergent synthesis of the C15−C38 domain of the marine natural product okadaic acid is reported. This involved the preparation of intermediates representing the C16−C27 and C28−C38 portions of okadaic acid, their direct coupling, and elaboration to the complete C15−C38 intermediate. A C16−C27 intermediate bearing an aldehyde at C27 was constructed in 14-steps from methyl 3-O-benzyl-α-d-altropyranoside
    报道了海洋天然产物冈田酸的 C15-C38 结构域的收敛合成。这涉及代表冈田酸的 C16-C27 和 C28-C38 部分的中间体的制备、它们的直接偶联以及对完整 C15-C38 中间体的加工。在 C27 处带有醛的 C16-C27 中间体由甲基 3-O-苄基-α-d-吡喃酮苷分 14 步构建而成。从 (S)-3-羟基-2-甲基丙酸甲酯分 10 个步骤制备 C28-C38 中间体,在 C28 处具有伯烷基溴。然后通过将溴化物转化为烷基铈试剂,然后添加到敏感的 β,γ-不饱和 C27 醛中以得到 C27 甲醇的混合物(27R:27S = 2.5:1),将这些片段以约 55% 的产率连接起来。主要偶联产物的 C27 处的构型通过简单的氧化还原序列反转,以建立冈田酸的 27S 构型。合成 C15 β-酮膦酸酯完成了全功能化的 C15-C38 p...
  • Synthetic Studies on Oligomycins. Synthesis of the Oligomycin B Spiroketal and Polypropionate Portions
    作者:Masaya Nakata、Takashi Ishiyama、Shinichi Akamatsu、Youichi Hirose、Hiroshi Maruoka、Rika Suzuki、Kuniaki Tatsuta
    DOI:10.1246/bcsj.68.967
    日期:1995.3
    The oligomycin B spiroketal portion, [2S,2(2R),3S,6R,8S,8(3R),9S,10R,11S]-2-[2-(t-butyldiphenylsilyloxy)propyl]-8-[3-(hydroxymethyl)pentyl]-3,9,11-trimethyl-1,7-dioxaspiro[5.5]undecane-5,10-diol (2), and polypropionate portion, ethyl (2E,4S,5R,6R,7S,8S,9R,10S,12R,13S,14R,16E)-5-(t-butyldimethylsilyloxy)7,9-(isopropylidenedioxy)-12,13-(4-methoxybenzylidenedioxy)-4,6,8,10,12,14-hexamethyl-11-oxo-18-phenylsulfonyloctadeca-2,16-dienoate (3), have been synthesized. The C19-C21 Wittig salt, [(2S,3R)-2-ethyl-3,4-(isopropylidenedioxy)butyl]triphenylphosphonium iodide (6), prepared from 2-butene-1,4-diol via Sharpless epoxidation, was coupled with the C22-C27 aldehyde, benzyl 2,4-dideoxy-3-O-(4-methoxybenzyl)-2,4-di-C-methyl-α,β-l-galacto-hexodialdopyranoside-(1,5) (7), prepared from (Z)-2-butene-1,4-diol via Sharpless epoxidation and the Brown’s crotylboration. The resulting coupling product was transformed to the C19-C27 lactone, [3S,4R,5R,6S,6(3R,4R)]-6-[3-ethyl-4,5-(isopropylidenedioxy)pentyl]-4-(4-methoxybenzyloxy)-3,5-dimethyl-3,4,5,6-tetrahydro-2H-pyran-2-one (4). The C28-C34 organostannane compound, (2R,4S,5S,7RS)-2-(t-butyldiphenylsilyloxy)-5-methyl-7-(tributylstannyl)-4-(triethylsilyloxy)-7-[(2-trimethylsilylethoxy)methoxy]heptane (5b), was prepared from (R)-methyl 3-hydroxybutyrate via the Brown’s crotylboration and the Still’s stannylation. After lithiation of 5b with butyllithium, the resulting α-alkoxy organolithium compound was coupled with 4 and the product was converted to the C19-C34 spiroketal, [2S,2(2R),3S,6R,8S,8(3R,4R),9S,10R,11S]-2-[2-(t-butyldiphenylsilyloxy)propyl]-8-[3-ethyl-4,5-(isopropylidenedioxy)pentyl]-10-(4-methoxybenzyloxy)-3,9,11-trimethyl-1,7-dioxaspiro[5.5]undecan-5-ol (37). The synthetic 2, derived from 37, was identical to the oligomycins (A, B, C mixture) degradation product in all respects, which elucidates the absolute stereochemistry of oligomycin B (1b). The C3-C9 aldehyde, (2-trimethylsilylethoxy)methyl 2,4,6-trideoxy-3-O-(4-methoxybenzyl)-2,4,6-tri-C-methyl-d-glycero-α-l-ido-heptodialdopyranoside-(1,5) (9), was prepared from (2S)-3-(t-butyldimethylsilyloxy)-2-methylpropanal via Keck’s crotylstannane addition and Brown’s crotylboration. The aldol coupling between the zinc enolate of the C10-C16 ketone, t-butyldimethylsilyl 2,3,7,8-tetradeoxy-4-O-(4-methoxybenzyl)-3,5-di-C-methyl-α-l-xylo-octopyranosid-6-ulose (10), prepared from methyl (R)-(+)-lactate via Brown’s crotylboration and a metallated methoxyallene addition, and aldehyde 9 gave the C8-C9 syn, C9-C10 syn product, which was transformed to the oligomycin B polypropionate portion 3 through elongation of the C1-C2 and C17-C18 carbon units.
