  Stereoselective synthesis of (−)-microcarpalide

  摘要：

  A stereoselective approach for the synthesis of the bio-active decanolactone (-)-microcarpalide was achieved from chiral pool tartaric acid. The synthesis of pivotal intermediates en route to the decanolactone was achieved from a-benzyloxy aldehydes derived from L- and D-tartaric acid. (c) 2006 Elsevier Ltd. All rights reserved.

  日期：2005.12

  Enantioselective synthesis of alpha-hydroxy aldehydes with an alkene tether was accomplished front L-(+)-tartaric acid, employing stereoselective reduction of a 1,4-diketone with L-selectride as the key step. Synthetic utility of these aldehydes was demonstrated in the synthesis of pine beetle pheromone (+)-exo-brevicomin. (c) 2005 Elsevier Ltd. All rights reserved.

  The enantioselective synthesis of alpha-benzyloxy aldehydes containing a terminal alkene was carried out from chiral Pool L-(+)tartaric acid by employing the stereoselective reduction of a 1,4-diketone as the key step. The synthetic utility of these aldehydes was demonstrated in the synthesis of pine beetle pheromones (+)-exo-brevicomin, (+)-iso-exo-brevicomin and a formal synthesis of 2,7cis-disubstituted oxepane (-)-isolaurepan.
