    Total Syntheses of Ipomoeassin B and E
    摘要:
    A concise, flexible, and efficient total synthesis of the cytotoxic resin glycosides ipomoeassin B (1) and ipomoeassin E (2) is reported which features the advantages of a novel protecting group strategy employing (Z)-3-dimethyl(phenyl)silyl-2-propenoic acid as cinnamic acid surrogate. The use of this readily available compound allowed the macrocycle of the glycolipids to be formed by ring closing olefin metathesis (RCM) with the aid of the second generation Grubbs carbene complex 12. The resulting E/Z mixture could be selectively hydrogenated using Wilkinson's catalyst [RhCl(PPh3)(3)] without affecting the unsaturated esters in the periphery of the compound, before the C-silyl group was cleaved off with TASF [tris(dimethylamino)sulfonium difluorotrimethylsilicate] under notably mild conditions to release the required cinnamate moiety. Other key steps of the synthesis route comprise the formation of the disaccharide linkage by the trichloroacetimidate method, the formation of the chiral acid segment 19 via a VO(acac)(2)-catalyzed, tert-BuOOH-induced oxidative rearrangement of the optically pure furyl alcohol (-)-15 (Achmatowicz-type reaction), and a reductive cleavage of the 4,6-O-p-methoxybenzylidene acetal in 5 with NaBH3CN and Me3SiCl (TMSCl), the regiochemical course of which was found to be opposite to that previously reported in the literature for sterically less encumbered substrates.

    细胞毒性树脂糖苷伊豆素A-F及其类似物的全合成及生物学评价
    摘要:
    使用现成的化合物26作为肉桂酸的替代品的多任务C硅烷化策略代表了树脂葡糖苷皂苷的所有已知成员的全合成的关键设计要素。这种保护基团的作用是使装饰目标葡萄糖亚基的不饱和酸在合成的早期阶段附着,防止它们参与用于形成大环的钌催化的闭环复分解(RCM),并保护它们防止在威尔金森氏催化剂上氢化所得环烯烃的过程中还原。由于C-甲硅烷基可随O-一起被去除在乙腈中使用三氟甲基丙烯酸三(二甲基氨基)ulf(TASF)的TBS取代基,在最后阶段不需要单独的保护基操作,因此有助于总体上有利的“步骤经济性”。除了天然存在的叶绿素外,还通过“转移总合成”制备了一小套合成类似物。用两种不同的癌细胞系测定了这些化合物的细胞毒性。记录的数据证实了先前的发现,即这些两亲性糖缀合物的酰化和氧合模式与它们的生物活性谱高度相关。事实证明,依泊豆素F是该系列中最有前途的成员,显示出低纳摩尔范围内的IC 50值。

  • Copper(II)-Catalyzed Silylation of Activated Alkynes in Water: Diastereodivergent Access to<i>E</i>- or<i>Z</i>-β-Silyl-α,β-Unsaturated Carbonyl and Carboxyl Compounds

    日期:2014.4.14
    Copper(II)‐catalyzed silylation of substituted alkynylcarbonyl compounds was investigated. Through the activation of Me2PhSiBpin in water at room temperature and open atmosphere, vinylsilanes conjugated to carbonyl groups are synthesized in high yield. A surprising diastereodivergent access to olefin geometry was discovered using a silyl conjugate addition strategy: aldehydes and ketones were Z selective
