  • Applications of Multicomponent Reactions for the Synthesis of Diverse Heterocyclic Scaffolds
    作者:James D. Sunderhaus、Chris Dockendorff、Stephen F. Martin
    DOI:10.1021/ol7018357
    日期:2007.10.1
    process involving sequential reactions of aldehydes, primary amines, acid chlorides, and nucleophiles has been developed to prepare multifunctional substrates that may be employed in subsequent ring-forming reactions to generate a diverse array of functionalized heterocyclic scaffolds. This new approach to diversity-oriented synthesis was then applied to the first total synthesis of the isopavine alkaloid
    已经开发了涉及醛,伯胺,酰氯和亲核试剂的顺序反应的四组分偶联工艺,以制备多功能底物,该多功能底物可用于随后的成环反应中,以生成各种功能化的杂环骨架。然后将这种面向多样性的合成的新方法应用于异戊烷生物碱(+/-)-roelactamine的第一个全合成。
  • Total Synthesis of (+)-Trienomycins A and F via C–C Bond-Forming Hydrogenation and Transfer Hydrogenation
    作者:David J. Del Valle、Michael J. Krische
    DOI:10.1021/ja4061273
    日期:2013.7.31
    The triene-containing C17-benzene ansamycins trienomycins A and F were prepared in 16 steps (longest linear sequence, LLS) and 28 total steps. The C11-C13 stereotriad was generated via enantioselective Ru-catalyzed alcohol CH syn crotylation followed by chelation-controlled carbonyl dienylation. Enantioselective Rh-catalyzed acetylene-aldehyde reductive coupling mediated by gaseous H2 was used to form
    含三烯的 C17-苯安沙霉素三烯霉素 A 和 F 以 16 个步骤(最长线性序列,LLS)和 28 个总步骤制备。C11-C13 立体三联体是通过对映选择性 Ru 催化的醇 CH 同步化生成,然后是螯合控制的羰基二烯化。由气态 H2 介导的对映选择性 Rh 催化乙炔-醛还原偶联用于形成二烯,该二烯最终经过二烯-二烯闭环复分解反应形成大环。本方法比以前合成的三烯霉素 A 和 F 短 14 步 (LLS),比任何以前合成的含三烯的 C17-苯安沙霉素短 8 步。
  • Pentadienyl Type Lithium and Potassium Species: The Regioselectivity of their Reactions with Electrophiles
    作者:Manfred Schlosser、Armin Zellner、Frédéric Leroux
    DOI:10.1055/s-2001-17521
    日期:——
    Seven structurally distinct pentadienyl type lithium and potassium compounds were screened against a variety of electrophiles in order to assess the regioselectivity of the trapping reactions. Organoborates and analogs thereof (fluorodimethoxyborane) proved to be perfectly regioreliable attacking only unsubstituted terminal positions and thus providing, after oxidation, exclusively primary allylic alcohols. 2,4-Pentadienyllithiums or -potassiums, that carry a methyl group at the 1- or 3-position, exhibit the same extreme regioselectivity towards halotrialkylsilanes or carbon dioxide. Although the unsubstituted parent compounds combine with such electrophiles still preferentially at the terminal position, considerable proportions of branched products are concomitantly formed as well (1/3-attack ratios ranging from 2:1 to > 20:1). Hydroxyalkylating and alkylating reagents such as formaldehyde, oxirane or butyl iodide invariably afford regioisomeric mixtures generally varying in composition between 3:1 and 1:3. The condensation reaction with halotrialkylsilanes appears to follow a concerted (SN2-like) rather than an addition/elimination (ate complex-mediated) mechanism.
    进行了七种结构不同的戊二烯基型锂和钾化合物的筛选,以评估它们与各种亲电试剂反应的区域选择性。有机硼酸盐及其类似物(氟二甲氧基硼烷)显示了非常可靠的区域选择性,仅攻击未取代的末端位置,因此氧化后只得到完全的一级烯丙基醇。带有甲基的2,4-戊二烯基锂或钾在1-或3-位置上,对卤代三烷基硅烷或二氧化碳显示出相同的极端区域选择性。尽管未取代的母体化合物仍优先在末端位置与这些亲电试剂反应,但同时也会生成相当比例的支链产物(1/3-攻击比例从2:1到超过20:1)。羟烷基化和烷基化试剂,如甲醛、环氧乙烷或丁基碘,总是得到区域异构体的混合物,其组成通常在3:1和1:3之间变化。与卤代三烷基硅烷的缩合反应似乎遵循协同(类似SN2)而非加成/消除(通过ate复合体介导)的机制。
  • Diastereoselective Pentadienylation Reaction of Protected Chiral α-Amino Aldehydes
    作者:Frédéric Minassian、Nadia Pelloux-Léon、Yannick Vallée
    DOI:10.1055/s-2000-6500
    日期:2000.2
    Diastereoselective pentadienylation of chiral α-amino aldehydes was achieved. The obtained anti amino alcohols can be transformed into dienic imines which undergo Diels-Alder cyclisation to give stereoselectively indolizidines.
    实现了手性α-氨基酸醛的非对映选择性戊二烯化。所获得的反式氨基醇可以转化为二烯亚胺,进而进行迪尔斯-阿尔德环加成反应,以选择性方式生成吲哚利西啶。
  • Lewis Acid-Mediated Carboxylation of Aryl- and Allylsilanes with Carbon Dioxide
    作者:Tetsutaro Hattori、Yutaka Suzuki、Sotaro Miyano
    DOI:10.1246/cl.2003.454
    日期:2003.5
    Aryl- and allylsilanes are carboxylated with CO2 with the aid of aluminum-based Lewis acids, to give aromatic and β,γ-unsaturated carboxylic acids in fair to good yields, respectively. Formation of the former is rationalized by an aromatic electrophilic substitution by CO2 activated by the Lewis acid, while the latter a nucleophilic addition of in situ-generated allylaluminum species to CO2.
    芳基和烯丙基硅烷在铝基路易斯酸的帮助下,与二氧化碳进行羧化反应,分别生成芳香族和β,γ-不饱和羧酸,产率从中等到良好。前者的形成可以通过路易斯酸激活的二氧化碳的芳香电亲核取代反应来合理解释,而后者则是原位生成的烯丙基铝物种对二氧化碳的亲核加成反应。
