Method of preparing retroviral protease inhibitor intermediates

   
   

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.

El isostere chiral del hydroxyethylamine, del hydroxyethylurea o del hydroxyethylsulfonamide que contiene el protease y los inhibidores retroviral del renin se puede preparar por las síntesis multi-step que utilizan los intermedios chiral dominantes de la amina. Esta invención es un método rentable de obtener tales intermedios chiral dominantes de la amina enantiomerically, diastereomerically y químicamente puros. El método es conveniente para las producciones de la escala grande (multikilogram). Esta invención también abarca el ácido orgánico y las sales ácidas inorgánicas de los intermedios de la amina.
