    from the F- and I-ring parts (6 and 5, respectively). The Nozaki–Hiyama–Kishi coupling of 6 with 5 followed by regio- and stereoselective epoxidation at C29 and C30 afforded an epoxide (4), which was transformed into a tricyclic compound (3) corresponding to the F-HI-ring part by 6-exo-epoxide opening and the subsequent inversion of the C29 stereocenter. Reductive cyclization of 3 forming the C31–O26
    瓜瓜毒素的普通FGHI环部分(2)已从F和I环部分(分别为6和5)合成。将Nozaki–Hiyama–Kishi由6与5偶联,然后在C29和C30进行区域选择性和立体选择性环氧化,得到环氧化物(4),该环氧化物转变为三环化合物(3),对应于F-HI环部分,为6 -外-epoxide开口和C29立构的后续反转。3形成G环的C31–O26键的3的还原环化成功产生2。
  • Convergent synthesis of the IJKLM-ring part of ciguatoxin CTX3C

    日期:2005.11
    Convergent synthesis of the IJKLM-ring part (2) of ciguatoxin CTX3C has been achieved from the I-ring and the L-ring parts (4 and 5) in total eight steps in 27% overall yield. The carbanion derived from 4, stabilized by a dimethyldithioacetal S-oxide group, was readily reacted with aldehyde 5 to give an adduct, which was facilely transformed into the corresponding alpha,epsilon-dihydroxy ketone 3. The JK-ring formation from 3 under reductive conditions followed by oxidative M-ring cyclization efficiently led to the pentacyclic ether 2. Improved synthesis of 6, a synthetic intermediate for 4, was also established. (c) 2005 Elsevier Ltd. All rights reserved.

    Convergent synthesis of the common FGHI-ring part (54) of ciguatoxins was achieved via the following key steps: (i) the Nozaki–Hiyama–Kishi reaction connecting the F-ring part (6) with the I-ring part (7); (ii) regio- and stereoselective epoxidation; (iii) the 6-exo-epoxide opening reaction forming simultaneously the H-ring and the quaternary asymmetric center at C30; (iv) inversion of the C29 stereocenter
    通过以下关键步骤实现了普通的瓜瓜毒素FGHI环部分(54)的收敛合成:(i)连接F环部分(6)和I环部分(7)的Nozaki–Hiyama–Kishi反应。; (ii)区域和立体选择性环氧化;(iii)在C30处同时形成H环和季不对称中心的6- exo- epoxy开环反应;(iv)通过两步氧化/还原过程使C29立构中心反转,其中成功的反转取决于对底物空间环境的适当管理;(v)最后的还原环化反应构建了G环。
