Preparation of optically-active di-(3-chloro-2-oxy-propyltrimethylammonium)-tartrate |
摘要 |
Process for the production of optically-active di-[3-chloro-2-oxy-propyltrimethylammonium]-tartrate. Racemic 3-chloro-2-oxy-propyltrimethylammonium-chloride is converted by racemate resolution with optically-active tartaric acid into the optically-active di-[3-chloro-2-oxy-propyltrimethylammonium]-tartrate. Such optically-active tartrate compound is dissociated in tartaric acid and optically-active 3-chloro-2-oxy-propyltrimethylammonium-chloride and the latter is converted with inorganic cyanides. From the product, the production of optically-active carnitine nitrile chloride can be achieved.
