  First total synthesis of tuberonic acid

  摘要：

  A vinyl group as an acetic acid side chain was attached to the optically active monoacetate of 4-cyclopentene-1,3-diol with CH2=CHMgBr, LiCl and a CuCN catalyst to produce the S(N)2-type product, from which the full carbon skeleton of tuberonic acid was constructed through Mitsunobu inversion, Claisen rearrangement, and Wittig reaction. At the last stage, the THP protective group was removed with MgBr2 in Et2O. The diastereomeric ratio of tuberonic acid and the trans isomer was 92:8 by H-1 NMR spectroscopy. (c) 2007 Elsevier Ltd.

  日期：2012.5

  The TES ether of the C6-hydroxy derivative of naturally occurring epi-jasmonic acid (epi-JA) was designed as epimerization-free equivalent of epi-JA. The TES ether was synthesized from (1R,4S)-4-hydroxycyclopent-2-enyl acetate in 13 steps. The acid part of the ether was activated with ClCO2Bui and subjected to condensation with l-amino acid at room temperature for 48 h. The TES group in the condensation

  epi-Jasmonic acid (epi-JA) and tuberonic acid (TA) were synthesized from the key aldehyde, all cis-2-(2-hydroxy-5-vinylcyclopentyl)acetaldehyde (14), which was in turn prepared stereoselectively from the (1R)-acetate of 4-cyclopentene-1,3-diol (10) through SN2-type allylic substitution with CH2CHMgBr followed by Mitsunobu inversion, Eschenmoser–Claisen rearrangement, and regioselective Swern oxidation

• Strategy for synthesis of the isoleucine conjugate of epi-jasmonic acid
  作者：Narihito Ogawa、Yuichi Kobayashi

  DOI：10.1016/j.tetlet.2008.09.144

  日期：2008.12

  The TES ether of 2-((1R,2S,3R)-3-hydroxy-2-((Z)-pent-2-enyl)cyclopentyl)acetic acid (5, equal to the reduction product of epi-jasmonic acid) derived from (1R,4S)-4-hydroxycyclopent-2-enyl acetate (19) in 13 steps was activated by using isobutyl chloroformate and was subjected to condensation with isoleucine at room temperature for 48 h. The product was desilylated and oxidized to the isoleucine conjugate of epi-jasmonic acid in 68% yield over three steps. Similarly, allo-isoleucine conjugate of epi-jasmonic acid and three isoleucine conjugates of ent-epi-jasmonic acid, jasmonic acid, and ent-jasmonic acid were synthesized. (C) 2008 Elsevier Ltd.
