  • A Facile and Efficient Synthesis of 4-Hydroxy-2,6-<i>cis</i>-tetrahydropyrans via Tandem Cross-Metathesis/Thermal S<sub>N</sub>2′ Reaction: Protecting-Group-Free Synthesis of (±)-Diospongin A
    作者:Kiyoun Lee、Hyoungsu Kim、Jiyong Hong
    DOI:10.1021/ol902125d
    日期:2009.11.19
    The tandem cross-metathesis/thermal SN2′ reaction was explored for the facile and efficient synthesis of 4-hydroxy-2,6-cis-tetrahydropyrans. The mildness of the thermal conditions allowed for the synthesis of 4-hydroxy-2,6-cis-tetrahydropyrans from base-sensitive substrates without the use of protecting groups. The tandem reaction enabled a protecting-group-free synthesis of (±)-diospongin A.
    探索了串联交叉复分解/热S N 2'反应的快速有效合成4-羟基-2,6-顺-四氢吡喃。热条件的温和性允许在不使用保护基的情况下从碱敏感的底物合成4-羟基-2,6-顺-四氢吡喃。串联反应使(±)-双倍体皂苷A的无保护基合成成为可能。
  • Iron-Catalyzed Synthesis of C2 Aryl- and <i>N</i>-Heteroaryl-Substituted Tetrahydropyrans

    DOI:10.1021/acs.joc.5b02371
    日期:2015.12.18
    An iron-catalyzed cyclization of hydroxy allylic derivatives into tetrahydropyrans possessing an N-heteroaryl at C2 is disclosed. The reaction proceeds with good yield and in high diastereoselectivity in favor of the more stable isomer. The diastereoselectivity results from an iron-induced reopening of the tetrahydropyrans, allowing a thermodynamic equilibration. The method allows access to a variety of 2,6-disubstituted as well as 2,4,6-trisubstituted tetrahydropyrans that could be considered as attractive scaffolds for the pharmaceutical industry.
  • Highly Enantioselective Acylation of Acyclic <i>Meso</i> 1,3-Diols through Synergistic Isothiourea-Catalyzed Desymmetrization/Chiroablative Kinetic Resolution

    日期:2015.5.1
    general and highly efficient organocatalyzed desymmetrization of acyclic meso 1,3-diols through acyl transfer using chiral isothioureas is described. The introduction of π-systems in the acyclic substrates provided new opportunities in terms of reactivity, enantioselectivity and synthetic potential. To reach this high level of enantioselectivity (up to er >99:1), the reaction proceeds through a synergistic
    描述了使用手性异硫脲通过酰基转移对无环内消旋1,3-二醇进行一般且高效的有机催化脱对称。在无环底物中引入π系统为反应性,对映选择性和合成潜力提供了新的机会。为了达到高水平的对映选择性(高达er> 99:1),反应通过协同机制进行,该机制涉及去对称化反应和手性动力学拆分过程。该方法成功地用作唯一的对映选择性催化步骤(以克为单位开发),以实现抗骨质疏松性二芳基庚烷(-)-双皂苷A的全合成(7个步骤)。
  • Stereoselective synthesis of (−)-diospongins A and B and their stereoisomers at C-5

    DOI:10.1016/j.tet.2007.06.081
    日期:2007.9
    Antiosteoporotic diarylheptanoids (−)-diospongins A (1) and B (2) were synthesized stereoselectively. The key steps in the synthesis include a stereospecific PdII-catalyzed cyclization of chiral 1,5,7-trihydroxy-2-heptenes, 6a and 6b, to form cis and trans tetrahydropyran rings and a regioselective Wacker oxidation of β-(tetrahydro-2H-pyran-2-yl)styrenes, 5a and 5b. Their C-5 epimers 3 and 4 were also
