  立体选择性合成两种高效的5-oxo-ETE受体拮抗剂

  摘要：

  描述了具有高水平对映体纯度的高效5-oxo-ETE受体拮抗剂5a和6a的对映选择性合成。这项工作的主要特点是简单有效地合成对映体比率为S / R：98.4 / 1.6的双官能化3-（S）-甲基戊二酸单甲酯（24）。我们研究了MeMgBr在CuBr /（S）-Tol-BINAP系统催化下的5-苯甲氧基-戊-2-烯酸甲酯（23）的不对称共轭加成反应，并优化了反应条件的区域选择性和高对映选择性。

  Two Potent OXE-R Antagonists: Assignment of Stereochemistry

  摘要：

  5-Oxo-6,8,11,14-eicosatetraenoic acid (5-oxo-ETE) is formed by the oxidation of 5-hydroxy-6E,8Z,11Z,14Z-eicosatetraenoic add (5-HETE), which is a major metabolite of enzymatic oxidation of arachidonic acid (AA). 5-Oxo-ETE is the most potent lipid chemoattractant for human eosinophils. Its actions are mediated by the selective OXE receptor, which is therefore an attractive target in eosinophilic diseases such as allergic rhinitis and asthma. Recently, we have reported two excellent OXE receptor antagonists that have IC50 values at low nanomolar concentrations. Each of these antagonists has a chiral center, and the isolation of the individual enantiomers by chiral high-performance liquid chromatography (HPLC) revealed that in each case one enantiomer is over 300 times more potent than the other. To unambiguously stereochemistry of these enantiomers and to provide access to larger amounts of the active compounds for biologicalassign the testing, we report here their total synthesis.
