  Homochiral 4-hydroxy-5-hexenoic acids and their derivatives and homologues from carbohydrates

  摘要：

  Efficient routes to chiral 4-hydroxy-5-hexenoic acids and lactones from D-gluconic acid-delta -lactone and L-mannonic acid-gamma -lactone are described. In this approach, the starting lactones are converted to 2,6-dibromo compounds that readily undergo zinc mediated elimination to generate the terminal alkene group in concert with 2-deoxygenation. The integrity of the remaining stereocenters is preserved during the reaction. The related important pharmaceutical intermediates (S)-3-hydroxy-4-pentenoic acid and (S)-1.3-dihydroxy-4-pentene were also prepared from 2-deoxyribose via the corresponding aldonolactone.

• Radical routes to indolizidines. Synthesis of (-)-slaframine
  作者：Spencer Knapp、Frank S. Gibson

  DOI：10.1021/jo00044a011

  日期：1992.8

  The synthesis of (-)-slaframine (5) was executed in 11 steps and 25% overall yield from resolved 3(S)-hydroxy-4-pentenamide (22). Two cyclization reactions were used to form the indolizidine skeleton and also to provide the necessary stereocontrol at C-8a and C-6 of the natural product. "Iodolactamization" of 22 gave selectively the cis-pyrrolidinone 21. Later in the synthesis, a silane-mediated radical cyclization of the phenylseleno lactam 33 gave selectively the 6-alpha-hydroxyindolizidinone 35a, an event predictable from model studies-such as 14c --> 15c. Replacement of hydroxy with azido and reduction of the lactam carbonyl gave "slaframine azide", 38, a stable and easily convertible immediate precursor to 5.
• Total Syntheses of Naturally Occurring Seimatopolide A and Its Enantiomer from Chiral Pool Starting Materials Using a Bidirectional Strategy

  日期：2012.12.7

  Enantioselective total syntheses of both enantiomers of the recently isolated decanolide natural product seimatopolide A are described. The C2-symmetric building blocks (R,R)-hexa-1,5-diene-3,4-diol (derived from d-mannitol) and its enantiomer (derived from l-(+)-tartrate) serve as key starting materials, which are elaborated in a bidirectional way using a selective mono-cross-metathesis, regio- and
