  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.

  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.
