  Conformationally restricted leukotriene antagonists. Synthesis of chiral 4-hydroxy-4-alkylcyclohexanecarboxylic acids as leukotriene D4 analogs

  摘要：

  Eight conformationally restricted LTD4 analogues, 2a-d (n = 1, 2), were prepared in nine steps from methyl 4-hydroxybenzoate (3). The key step in this approach is the Sharpless asymmetric epoxidation of allylic alcohol 8 in which all four possible epoxy alcohol diastereomers 9a-d were prepared. A single-crystal X-ray analysis of 9b and application of the Sharpless model for predicting epoxidation stereoselectivity led to the assignment of relative stereochemistry and absolute configuration of 9a-d. These high optical purity epoxy alcohols were then converted to chiral LTD4 analogues 2a-d (n = 1, 2) in three steps.
