  • Total Syntheses of Allelopathic 4-Oxyprotoilludanes, Melleolides, and Echinocidins
    作者:Kazuma Shimoda、Yousuke Yamaoka、Dongeun Yoo、Ken-ichi Yamada、Hiroshi Takikawa、Kiyosei Takasu
    DOI:10.1021/acs.joc.9b01589
    日期:2019.9.6
    with an angular hydroxy group was built via three key transformations: (1) Me3Al-catalyzed [2 + 2] cycloaddition of a ketene silyl acetal with a propiolate, (2) reductive ring-opening of a cyclic hemiketal, and (3) the intramolecular Morita–Baylis–Hillman reaction. This synthetic route represents a new and reliable strategy to obtain protoilludanes with several oxy-functional groups.
    实现了立体控制的化感性4-氧原丙二酮倍半萜,美洛肽,美洛肽F以及棘孢菌素B和D的立体合成。弯曲的5/6/4具有角羟基的三环系统是通过以下三个关键转化构建的:(1)Me 3 Al催化的[2 + 2]烯酮甲硅烷基缩醛与丙酸酯的环加成反应,(2)还原环-环状半水合物的开放,以及(3)分子内的Morita–Baylis–Hillman反应。该合成路线代表了一种新的,可靠的策略来获得具有几个氧官能团的原illilludanes。
  • Enantioselective synthesis of cis-1,2-dialkyl substituted cyclopentanoid and isoprostane building blocks via 6-exo-trigonal radical cyclizations
    作者:Giuseppe Zanoni、Savino Re、Alessia Meriggi、Francesca Castronovo、Giovanni Vidari
    DOI:10.1016/s0957-4166(01)00312-3
    日期:2001.7
    Two different 6-exo-trigonal cyclizations of enantiomerically enriched 6-heptenyl radicals readily afforded versatile synthetic precursors of cis-1,2-dialkyl substituted cyclopentane derivatives. Starting from one of these intermediates, we accomplished an enantiospecific formal synthesis of two important isoprostanes, namely 15-F-2c-IsoP and ent-15-F-2c-IsoP. (C) 2001 Elsevier Science Ltd.

  • A facile stereoselective synthesis of (3aR*,4R*,6aS*)-4-(hydroxymethyl)- 3,3a,4,6a-tetrahydrocyclopenta[b]furan- 2-one and other useful cyclopentanoid building blocks.

  • Enantioselective syntheses of isoprostane and iridoid lactones intermediates by enzymatic transesterification
    作者:Giuseppe Zanoni、Fabio Agnelli、Alessia Meriggi、Giovanni Vidari
    DOI:10.1016/s0957-4166(01)00311-1
    日期:2001.7
    Crude Pseudomonas cepacia lipase (Amano PS-30) is a suitable biocatalyst for the kinetic resolution of the 1,2-cis-disubstituted cyclopentanoid building block (3aR*,4R*,6aS*)-(+/-)-4-hydroxymethyl-3,3a,4,6a-tetrahydrocyclopenta[b]furan-2-one through enantioselective transesterification. Enantiomerically enriched acetic acid (3aS,4S,6aR)-(+)-2-oxo-3,3a,4,6a-tetrahydro2H-cyclopenta[b]furan-4-yl methyl ester was utilized in a formal synthesis of the iridoids (+)-isoiridomyrmecin and (-)-teucrium-lactone.

  • Diastereocontrol in Lewis acid-catalyzed Michael reactions of 4-siloxycyclopentenone with ketene silyl acetals: Stereoelectronic vs. steric effect
    作者:Junzo Otera、Yukihiro Fujita、Shunichi Fukuzumi、Kei-ichi Hirai、Jin-Hua Gu、Takeshi Nakai

    are shown to proceed with sterically unfavorable syn preference (to the siloxy group) when steric demand of the acetals is trivial, whereas β-substitution of acetals results in reversal of diastereoselection. These results are discussed in terms of the stereoelectronic vs. steric effect.
    当乙缩醛的空间需求微不足道时,标题反应显示出在空间上不利的顺式(相对于甲硅烷氧基)的进行,而乙缩醛的β-取代导致非对映选择性的逆转。这些结果将根据立体电子与空间效应进行讨论。
