  Synthesis and Absolute Configuration of Zonarol. A Fungitoxic Hydroquinone from the Brown Seaweed Dictyoptfris Zonarioides(1)

  摘要：

  AbstractA total synthesis of both the enantiomers of zonarol 1 was accomplished. Measurements of the ORD‐CD spectra of two bicyclic intermediates coupled with direct comparison of the natural and synthetic zonarol 1 established the absolute configuration of the naturally occurring (+)‐zonarol 1 as 1R, 4aR, 8aR.

• Synthesis of decalin type chiral synthons based on enzymatic functionalisation and their application to the synthesis of (−)-ambrox and (+)-zonarol
  作者：Hiroyuki Akita、Masako Nozawa、Hiroyo Shimizu

  DOI：10.1016/s0957-4166(98)00172-4

  日期：1998.5

  Stereoselective syntheses of (−)-ambrox 2 and (+)-zonarol 3 were achieved based on the enzymatic syntheses of (8aS)- and (8aR)-decalin-type 1,3-diols 1, respectively. Non-racemic intermediates such as (8aS)-1 and (8aR)-1 were obtained based on the enantioselective hydrolyses of the phenolic acetal derivative (±)-7 by acylase I.

  （-）-ambrox 2和（+）-zonarol 3的立体选择性合成分别基于（8a S）-和（8a R）-萘烷型1,3-二醇1的酶促合成而实现。基于酚醛缩醛衍生物（±）-7被酰基转移酶I的对映选择性水解，获得了非外消旋中间体，例如（8a S）-1和（8a R）-1。
• Total synthesis of yahazunol, zonarone and isozonarone
  作者：Thorsten Laube、Jörg Schröder、Ralf Stehle、Karlheinz Seifert

  DOI：10.1016/s0040-4020(02)00346-0

  日期：2002.5

  The synthesis of the marine natural products zonarone and isozonarone was achieved via (+)-albicanic acid, a sesquiterpene of the drimane type. Coupling of the appropiate drimane-synthon with lithiated hydroquinone ethers led to sesquiterpene arenes, which were further modified to the target molecules. Stereoselective epoxidation followed by regioselective opening of the oxirane ring yielded yahazunol. (C) 2002 Elsevier Science Ltd. All rights reserved.
