  Absolute stereochemistry and conformational analysis of achaetolide isolated from Ophiobolus sp.

  摘要：

  Achaetolide, as reported by Bodo et al. in 1983, was isolated from a fermentation broth of Ophiobolus sp. We established the absolute stereochemistry of achaetolide to be 3S,6R,7S,9R by way of relative stereochemical assignment with H-1 NMR analyses employing the corresponding acetonide, determination of C3 and C9 stereochemistries by an extended Mosher method.

  The stereoselective total synthesis of (−)-achaetolide

  摘要：

  The stereoselective total synthesis of (-)-achaetolide is described in a convergent manner. Grignard addition, Wittig homologation, acetate aldol and ring closing metathesis reactions were the key steps involved. The required olefinic alcohol fragments were synthesized from a single chiral pool material 2-deoxy-D-ribose and olefinic acid fragment was prepared from acetate aldol reaction. Both the olefinic acid and alcohols were prepared in a concise method. (C) 2012 Elsevier Ltd. All rights reserved.

  Synthesis of chiral tetrols and 1,2,4-triols with varied substitutions was accomplished from tartaric acid. Pivotal reaction in the synthesis was the use of Ley's dithianylation of an alkynyl ketone derived from tartaric acid. Application of the strategy was demonstrated in the total synthesis of decanolactone achaetolide.

  A highly convergent stereoselective total synthesis of achaetolide, a ten-membered lactone is described. The ring-closing metathesis reaction was used to construct the macrocycle and E-olefinic moiety in the molecule. The key acid and alcohol fragments were synthesized from a single chiral pool material D-mannitol.

  A convergent total synthesis of achaetolide is described. The key steps include a Horner-Wadsworth-Emmons olefination, CBS reduction to install the stereochemistry at the C9 center, ste­reoselective vinylation to introduce the chiral center at C6, and finally­ a ring-closing metathesis (RCM) reaction to construct the ten-membered lactone of the molecule. macrocycles - metathesis - stereoselective synthesis

  The first total synthesis of achaetolide, a 10-membered macrolactone was achieved using Mitsunobu reaction and Grubbs ring-closing metathesis reaction as the key steps for ring construction. The desired stereo centres were generated by Jacobsen hydrolytic kinetic resolution, dihydroxylation and Sharpless asymmetric epoxidation reactions. (c) 2010 Elsevier Ltd. All rights reserved.
• First asymmetric synthesis of achaetolide
  作者：Tapas Das、Rajib Bhuniya、Samik Nanda

  日期：2010.9

  The first asymmetric synthesis of the 10-membered macrolide achaetolide is reported in this article. The main highlight of the synthetic strategy is the ring-closing metathesis (RCM) of intermediate 19, which in turn can be accessed from coupling between alcohol 11 and acid 18. The synthesis of 11 involves enzymatic kinetic resolution (EKR) coupled with a Mitsunobu inversion strategy, while 18 can be prepared by adopting a metal-enzyme combined dynamic kinetic resolution (DKR) reaction followed by functional group manipulation.
