  • Asymmetric Synthesis of 4,5-Disubstituted 3-Hydroxy δ-Lactones: Prelactone B and Prelactone V
    作者:Dieter Enders、Mareile Haas
    DOI:10.1055/s-2003-42060
    日期:——
    An efficient asymmetric synthesis of δ-lactones such as prelactone B has been developed. As key steps, the SAMP/RAMP-hydrazone methodology for the synthesis of 2-methylenated 1,3-diols and a homogenous hydrogenation were used.
    已开发出一种高效的 β-内酯(如前内酯 B)不对称合成方法。作为关键步骤,使用了合成 2-亚甲基化 1,3-二醇的 SAMP/RAMP-腙方法和均相氢化。
  • A general synthetic approach for the synthesis of β-hydroxy-δ-lactones: asymmetric total synthesis of prelactones and epi-prelactones V and E

    A general synthetic approach for the synthesis of prelactones and epi-prelactones V and E has been reported using an Evans’ aldol reaction as the key step.
    已经报道了使用埃文斯的醛醇缩合反应作为关键步骤来合成prelactones和epi- prelactones V和E的通用合成方法。
  • A convergent route to β-hydroxy δ-lactones through Prins cyclisation as the key step: synthesis of (+)-prelactones B, C and V
    作者:J.S. Yadav、M. Sridhar Reddy、A.R. Prasad
    DOI:10.1016/j.tetlet.2005.01.121
    日期:2005.3
    Reactions of homoallylic alcohols with aldehydes in the presence of acid catalysts gave multisubstituted tetrahydropyrans with the creation of one to three new stereogenic centres in a single-pot process. The utility of this approach is extended to the enantioselective syntheses of (+)-prelactones B, C and V. (C) 2005 Elsevier Ltd. All rights reserved.
  • Total syntheses of Prelactone V and Prelactone B

    products Prelactone-V and Prelactone-B have been accomplished by a novel Chiron approach starting from d-glucose. The synthesis involves isopropylidene acetal formation of d-glucose using Poly(4-vinylpyridine) supported iodine as a catalyst, Tebbe olefination, Grignard reaction, Wittig olefination, selective mono deprotection of acetal using PMA/SiO2, hydrogenation and anti-1,3-diol formation are as
    天然产物Prelactone-V和Prelactone-B的总合成已通过从d-葡萄糖开始的新型Chiron方法完成。合成涉及使用聚(4-乙烯基吡啶)负载的碘作为催化剂的D-葡萄糖的异亚丙基缩醛形成,Tebbe烯烃化,Grignard反应,Wittig烯烃化,使用PMA / SiO2进行的乙醛选择性单脱保护,氢化和抗1,3-3二醇的形成是关键步骤。
