Patent number: 6682916Abstract: A process for efficiently preparing an optically active chloropropanediol derivative, especially (S)-1-benzyloxy-3-chloro-2-propanol, which has a high optical purity and is useful as an intermediate for medicines. The process comprises treating an inexpensive racemic chloropropanediol derivative with a nitroxyl compound and an oxidizing agent to convert it into a chlorohydroxyacetone derivative and then stereospecifically reducing the carbonyl group of the chlorohydroxyacetone derivative by the action of either a carbonyl-reducing enzyme having the ability to stereospecifically reduce the chlorohydroxyacetone derivative or an optically treated culture of a microorganism having the ability to yield the carbonyl-reducing enzyme. Thus, an optically active chloropropanediol derivative is prepared.Type: GrantFiled: February 26, 2002Date of Patent: January 27, 2004Assignee: Kaneka CorporationInventors: Naoaki Taoka, Hironobu Maeda, Kazumi Okuro, Koichiro Toyota, Yoshihiko Yasohara
