  A highly convergent synthesis of the macrolide natural product milbemycin β1 is reported. The key features of this synthesis include the introduction of the C11-C15 side chain by selective ring opening of a symmetrical 1,4-pentane bis-epoxide (3) followed by reaction with the anion derived from the 2,3-trans-dimethyl-6-phenylsulphonyl pyran (2) to afford the “northern” C11-C25 fragment (33) of milbemycin

  strategy, two fragments of β-d-mannosyl phosphomycoketide (C32-MPM) and four stereopure 1,5-dimethylalkane C10 chirons are prepared. These C32-MPM fragments and C10 chirons have shown great potential application as building blocks for the synthesis of highly methyl-branched natural products containing chiral oligoisoprenoid-like chains.

• Tumescenamide C, an antimicrobial cyclic lipodepsipeptide from Streptomyces sp.

  Tumescenamide C, a new cyclic lipodepsipeptide, was isolated from a culture broth of an actinomycete Streptomyces sp. KUSC_F05. Tumescenamide C was a congener of tumescenamides A and B, representing a sixteen-membered ring system, consisting of two proteinogenic and three non-proteinogenic amino acids, to which a methyl-branched fatty acid was attached. The planar structure was determined by spectroscopic analysis, while its absolute stereochemistry was determined by chemical degradation and asymmetric synthesis. Tumescenamide C exhibited antimicrobial activity with high selectivity against Streptomyces species. (c) 2012 Elsevier Ltd. All rights reserved.
• Highly Stereocontrolled Total Synthesis of β-<scp>d</scp>-Mannosyl Phosphomycoketide: A Natural Product from <i>Mycobacterium tuberculosis</i>
  作者：Nan-Sheng Li、Louise Scharf、Erin J. Adams、Joseph A. Piccirilli

  beta-D-Mannosyl phosphomycoketide (C-32-MPM), a naturally occurring glycolipid found in the cell walls of Mycobacterium tuberculosis, acts as a potent antigen to activate T-cells upon presentation by CD1c protein. The lipid portion of C-32-MPM contains, a C-32-mycoketide, consisting of a saturated oligoisoprenoid chain with five chiral methyl branches. Here we develop several stereocontrolled approaches to assemble the oligoisoprenoid chain with high stereopurity (>96%) using Julia-Kocienski olefinations followed by diimide reduction. By careful choice of olefination sites, we could derive all chirality from a single commercial compound, methyl (2S)-3-hydroxy-2-methylpropionate (>99% ee). Our approach is the first highly stereocontrolled method to prepare C-32-MPM molecule with >96% stereopurity from a single >99% ee starting material. We anticipate that our methods will facilitate the highly stereocontrolled synthesis of a variety of other natural products containing chiral oligoisoprenoid-like chains, including vitamins, phytol, insect pheromones, and archaeal lipids.
