  Total synthesis, elucidation of absolute stereochemistry, and adjuvant activity of trihydroxy fatty acids

  摘要：

  Pinellic acid from the tuber of Pinellia ternate, an active herbal component of the traditional Japanese herbal (Kampo) medicine Sho-seiryu-to, is a C18 trihydroxy fatty acid whose absolute stereochernistry has now been determined. All stereoisomers of pinellic acid were synthesized via regioselective asymmetric dihydroxylation, regioselective inversion, and stereoselective reduction in order to determine their absolute stereochemistries and adjuvant activities. Among this series of isomers, the (9S,12S,13S)-compound, which is a natural product, exhibited the most potent adjuvant activity. Spectral data for all of the stereoisomers of the 1,2-allylic diols were compared and related to their stereochemistries. (c) 2006 Published by Elsevier Ltd.

  The stereoselective total synthesis of (+)-pinellic acid, a natural product used in the treatment of influenza, was accomplished from l-(+)-tartaric acid. A key feature of the synthesis includes the elaboration of a γ-hydroxybutyramide derived from l-(+)-tartaric acid.

  Pinellic acid is a novel and potentially useful oral adjuvant when used in conjunction with intranasal inoculation of influenza HA vaccines. All stereoisomers of pinellic acid have been synthesized via regioselective asymmetric dihydroxylation, regioselective inversion, and stereoselective reduction, and their adjuvant activities were characterized. Among this series of isomers, 9S, 12S, 13S compound

  松果酸与鼻内接种HA流感疫苗一起使用时，是一种新颖且可能有用的口服佐剂。已通过区域选择性不对称二羟基化，区域选择性反转和立体选择性还原合成了所有松果酸立体异构体，并对其佐剂活性进行了表征。在这一系列异构体中，9S，12S，13S化合物具有最强的佐剂活性。讨论了构效关系。

  A straightforward strategy for the synthesis of (+)-pinellic acid in 16% overall yield and 13 steps, starting from (1R)-1-(furan-2-yl)hexan-1-ol, is described. Key reactions in the synthesis include a Sharpless kinetic resolution, oxidation of a protected furan to reveal a but-2-ene-1,4-dione moiety, and an asymmetric reduction.
