  Total Synthesis of Ciguatoxin and 51-HydroxyCTX3C

  摘要：

  Ciguatoxins, the principal causative toxins of ciguatera seafood poisoning, are large ladder-like polycyclic ethers with the 13 ether rings ranging from five- to nine-membered. In this paper, we describe the total synthesis of the two most toxic members of the ciguatoxin family, ciguatoxin 1 and 51-hydroxyCTX3C 2, based on a unified synthetic strategy. The key features in our syntheses were (i) direct construction of the O,S-acetal from the corresponding left and right wing fragments (3, 4, 14); (ii) stereo- and chemoselective radical reaction of the alpha-oxyradical with pentafluorophenyl acrylate to achieve cyclization of the seven-membered G-ring; (iii) ring-closing metathesis reaction to build the nine-membered F-ring; and (iv) an efficient protective group strategy using the oxidatively removable 2-naphthylmethyl groups.

  51-hydroxyCTX3C was developed in which oxiranyl anion addition and intramolecular carbonyl olefination were utilized as key transformations. The present procedure requires only 23 steps from the I-ring 5, while 35 steps were employed in a previous synthesis of the corresponding right wing 11 of CTX3C. The high efficiency of the present synthesis ensures a supply of 10 for total synthesis and biomedical applications

  of ciguatoxins were synthesized highly stereoselectively. Key transformations in the synthesis are (i) an oxiranyl anion strategy to attach the H ring, (ii) intramolecular carbonyl olefination to cyclize the J ring, (iii) regio- and stereoselective reduction of the epoxyacetal to install the C42-stereocenter, and (iv) stereoselective reductive etherification to construct the K ring. The present procedure

  高立体选择性地合成了瓜瓜毒素的右翼（13和14）。合成中的关键转变是（i）连接H环的环氧乙烷基阴离子策略，（ii）分子内羰基烯化以使J环环化，（iii）环氧乙缩醛的区域和立体选择性还原以安装C42-立体中心和（iv）立体选择性还原醚化以构建K环。与先前的合成方法相比，本方法大大提高了立体选择性和效率。值得注意的是，单环I环5仅需23个步骤建造雪茄毒素的右翼。本合成的高度实用性确保了这些复杂片段的充分供应，以用于总合成和生物医学应用。
