Chiral hydroxyethylamine, hydroxyethylurea or hydroxyethylsulfonamide isostere containing retroviral protease and renin inhibitors can be prepared by multi-step syntheses that utilize key chiral amine intermediates. This invention is a cost effective method of obtaining such key chiral amine intermediates enantiomerically, diastereomerically and chemically pure. The method is suitable for large scale (multikilogram) productions. This invention also encompasses organic acid and inorganic acid salts of the amine intermediates.
手性羟乙基胺、羟乙基脲或羟乙基磺酰胺异构体,包含逆转录病毒蛋白酶和肾素抑制剂,可以通过多步合成制备,利用关键的手性胺中间体。本发明是一种经济有效的方法,可以对这些关键的手性胺中间体进行对映异构体、顺反异构体和化学纯度的制备。该方法适用于大规模(多千克级别)生产。本发明还包括胺中间体的有机酸和无机酸盐。
