  Enantioselective Total Syntheses of (−)-7βH-Eudesmane-4α,11-diol and (+)-ent-7βH-Eudesmane-4α,11-diol

  摘要：

  The syntheses of (-)-7 beta H-eudesmane-4 alpha,11-diol (2) and (+)-ent-7 beta H-eudesmane-4 alpha,11-diol (ent-2) were carried out starting from (-)- and (+)-dihydrocarvones. As a result, the structure, including absolute configuration, of the naturally occurring eudesmane-4,11-diol isolated from Pluchea arguta was determined to be (+)-ent-7 beta H-eudesmane-4 alpha,11-diol (ent-2).

• Stereoselective synthesis of (–)-4-epiaxinyssamine
  作者：Leonardo Castellanos、Carmenza Duque、Jaime Rodríguez、Carlos Jiménez

  DOI：10.1016/j.tet.2006.12.019

  日期：2007.2

  The synthetic studies towards axinyssamine, a cytotoxic and coral-lethal compound isolated from the Caribbean sponge Axinyssa ambrosia were performed. The Ritter reaction on the key intermediate with chloroacetonitrile, resulted in the introduction of the amino group at C-4 generating the configuration of this stereocentre opposite to that of the natural product. As a result, the first total synthesis of the unnatural (-)-4-epiaxinyssamine was achieved. (c) 2006 Elsevier Ltd. All rights reserved.
