  • Synthetic studies of mycalolide B, an actin-depolymerizing marine macrolide: construction of the tris-oxazole macrolactone using ring-closing metathesis
    作者:Masaki Kita、Hidekazu Watanabe、Tomoya Ishitsuka、Yuzo Mogi、Hideo Kigoshi
    DOI:10.1016/j.tetlet.2010.07.046
    日期:2010.9
    Tris-oxazole macrolactone 2, a key intermediate of mycalolide B (1), which has 13 stereogenic centres, was synthesized through the use of ring-closing metathesis (RCM). The E/Z ratio of the RCM product 2 was reversed by the use of CH(2)Cl(2) and toluene, whereas a cross-metathesis reaction yielded the C1-C35 long-chain compound 19 in a highly E-selective manner. Thus, the loss of flexibility in aliphatic carbon chains and the steric hinderance of beta- and gamma-substituents of the C20 olefin in the precursor 11 may affect the stereoselectivity in RCM reactions.

  • Total Synthesis of (+)-Acutiphycin
    作者:Ryan M. Moslin、Timothy F. Jamison
    DOI:10.1021/jo701821h
    日期:2007.12.1
    [GRAPHICS]Synthetic studies toward the total synthesis of (+)-acutiphycin (1) resulted in the discovery of additive-free, highly regioselective nickel -catalyzed reductive coupling reactions of aldehydes and 1,6-enynes and the construction of an advanced intermediate in studies directed toward the synthesis of 1. Ultimately, although not employing the nickel-catalyzed reaction, a highly convergent total synthesis of (+)-acutiphycin featuring an intermolecular SMI2-mediated Reformatsky coupling reaction and macrolactonization initiated by a retro-ene reaction of an alkoxyalkyne was achieved. The resulting synthesis was 18 steps in the longest linear sequence from either methyl acetoacetate or isobutyraldehyde.
  • Toward the total synthesis of lophotoxin — New methodologies and synthetic strategies
    作者:Peter Wipf、Michel Grenon
    DOI:10.1139/v06-073
    日期:2006.10.1
    progress toward the synthesis of the furanocembranolide lophotoxin (1) is disclosed. Strategies for the stereoselective incorporation of the C13 stereocenter by a catalytic desymmetrization of a cyclic meso-anhydride, as well as a novel 1,6-addition reaction of organocuprates to unsaturated [1,3]dioxin-4-ones are discussed. Preliminary results on the development of a rhodium-catalyzed asymmetric 1,6-addition
    我们最近在合成呋喃西姆内酯 lophotoxin (1) 方面取得了进展。讨论了通过环状内消旋酸酐的催化去对称化立体选择性结合 C13 立体中心的策略,以及有机铜酸盐与不饱和 [1,3] 二恶英 4-ones 的新型 1,6-加成反应。还提到了开发铑催化的不对称 1,6-加成反应的初步结果。最后,对先前报道的涉及 α-炔丙基 β-酮酯的过渡金属催化环化反应的改进,允许在热条件下或通过微波辐射形成呋喃环。 关键词:1,6-加成,有机铜酸盐,催化去对称化,呋喃环化,微波。
  • Highly Convergent Total Synthesis of (+)-Acutiphycin
    作者:Ryan M. Moslin、Timothy F. Jamison
    DOI:10.1021/ja0670660
    日期:2006.11.1
    enantioselective, convergent, total synthesis of (+)-acutiphycin (18 steps, longest linear sequence from commercial materials) features the first application of an alkynyl ether as a macrolactone precursor in total synthesis, as well as the first example of an intermolecular, SmI2-mediated, Reformatsky fragment coupling reaction. The high convergence, efficiency, and modular nature of this synthesis make it
    (+)-acutiphycin 的对映选择性、收敛、全合成(18 步,来自商业材料的最长线性序列)的特点是炔基醚作为大环内酯前体在全合成中的首次应用,以及分子间的第一个例子, SmI2 介导的 Reformatsky 片段偶联反应。这种合成的高收敛性、效率和模块化性质使其适合合成结构相关的化合物。
