described. The synthetic route provided MK-1597 in nine steps and 29% overall yield from commercially available p-cresol (7). The key features of this sequence include a catalytic asymmetric hydrogenation of a tetrasubstituted ene−ester, a highly efficient epimerization/saponification sequence of 4 which sets both stereocenters of the molecule, and a short synthesis of amine fragment 2.
描述了实用的对映体选择性合成肾素抑制剂MK-1597(ACT-178882),这是一种潜在的高血压新疗法。合成路线以九个步骤提供了MK-1597,从商业上可获得的对甲酚(7)的总产率为29%。该序列的关键特征包括四取代烯酯的催化不对称氢化,高效的差向异构化/皂化序列4(可设置分子的两个立体中心)和胺片段2的短合成。
