    摘要: The present invention relates to a method for producing an L-amino acid by reacting an enantiomeric mixture of an N-succinyl amino acid with L-succinylase in the presence of N-acylamino acid racemase to specifically hydrolyze the L-form. In particular, the present invention relates to a method for producing an L-amino acid in high yield by using an N-succinyl amino acid whose dissolved concentration is particularly low as a raw material to perform a reaction while precipitating the produced L-amino acid out of the reaction system. The present invention enables efficient production of an L-amino acid having high optical purity, particularly an L-amino acid useful as a raw material for products such as pharmaceutical products and agricultural chemicals.

    摘要: The present invention provides a method enabling convenient production of an optically active secondary alcohol useful as a pharmaceutical intermediate, particularly an optically active 1,2-diol and an optically active 2-alkanol, from an enantiomer mixture thereof. An oxidizing enzyme source having the capability of selectively oxidizing one enantiomer of secondary alcohol is allowed to act on an enantiomer mixture of secondary alcohol in the presence of a reducing enzyme source having the capability of reverse enantio-selectively reducing a ketone derivative, to convert the enantiomer mixture into a substantially single enantiomer at a theoretical percent recovery of 100%, whereby an optically active secondary alcohol is produced.

    摘要: 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.

    摘要: An objective of the present application is to provide an industrially practicable method for producing an optically-active 3-amino-2-hydroxypropionic cyclopropylamide derivative or salt thereof from an inexpensive easily-available starting material. The derivative or salt thereof is useful as an intermediate for a medicine. It is also intended by the present application to provide a useful intermediate of the derivative. The objective is attained by the following method. First, an easily-available 2-halo-3-oxopropionic acid derivative is asymmetrically reduced, and then epoxidated to produce an optically-active epoxycarboxylic acid derivative. Next, the derivative is converted into an optically-active epoxyamide derivative by reaction with cyclopropylamine, and then reacted with a nitrile to obtain an optically-active oxazolinamide derivative. Subsequently, selective acid solvolysis of the oxazoline skeleton gives the optically-active 3-amino-2-hydroxypropionic cyclopropylamide derivative or salt thereof.
