  A Practical Synthesis of 5-Lipoxygenase Inhibitor MK-0633

  摘要：

  Practical, chromatography-free syntheses of 5-lipoxygenase inhibitor MK-0633 p-toluenesullonate (1) are described. The first route used an asymmetric zincate addition to ethyl 2,2,2-trifluoropyruvate followed by 1,3,4-oxadiazole formation and reductive amination as key steps. An improved second route features an inexpensive diastereomeric salt resolution of vinyl hydroxy-acid 22 followed by a robust end-game featuring a through-process hydrazide acylation/1,3,4-oxadiazole ring closure/salt formation sequence to afford MK-0633 p-toluenesulfonate (1).
