• Total Synthesis of Halicholactone and Neohalicholactone¹

  DOI：10.1021/jo962312j

  日期：1997.9.1

  The total synthesis of the marine natural products neohalicholactone (1) and halicholactone (2), in enantiomerically pure form, are reported. Key steps in the synthesis of each compound include a cis-selective Wittig reaction, stereoselective cyclopropanation, nine-membered lactone formation using the Yamaguchi method and late-stage stereoselective Cr(II)/Ni(II) mediated coupling of vinyl iodides 39 and 50 with aldehyde 14. In the case of the neohalicholactone synthesis the two major components which were coupled in this convergent synthesis were each derived from the enantiomers of commercially available malic acid. The synthesis served to confirm the original assignment of absolute configuration which was made by Yamada and Clardy. We also demonstrated, through the preparation of diastereoisomers, that another reported compound closely related to neohalicholactone is likely to be the C-15 epimer 67.
• Synthetic studies toward the microtubule-stabilizing agent laulimalide: synthesis of the C15–C28 fragment
  作者：B.Travis Messenger、Bradley S Davidson

  日期：2001.1

  The C15–C28 fragment of the paclitaxel-like antimicrotubule agent laulimalide has been synthesized in 12 linear steps with an overall yield of 14%. The methyldihydropyran ring of the side chain was efficiently prepared using ring-closing olefin metathesis chemistry and the 19,20-syn-diol was generated through the addition of a mixed vinyl zincate to a protected α-hydroxyaldehyde.

  紫杉醇样抗微管药laulimalide的C 15 –C 28片段已通过12个线性步骤合成，总产率为14％。使用闭环烯烃复分解化学有效地制备了侧链的甲基二氢吡喃环，并且通过将混合的乙烯基锌酸酯添加至受保护的α-羟基醛中来生成19,20-顺式-二醇。
