摘要： A 2- or 4-nitrobenzenesulfonamide is allowed to react with an alkali metal alkoxide to remove a nitrobenzenesulfonyl group to thereby obtain an amine corresponding to the amide. Furthermore, a method for producing an amine derivative by allowing the resulting amine without isolation to react with an activated, substituted oxycarbonyl compound or an activated acyl compound is provided. According to this method, a corresponding free amine and its substituted derivative can be produced easily and industrially advantageously from the 2- or 4-nitrobenzenesulfonamide without using a thiol compound.

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.

摘要： A process for easily producing an optically active β-amino alcohol useful as a pharmaceutical intermediate from an inexpensive, readily available starting material is provided. A readily available α-substituted ketone is reacted with an optically active amine to yield a diastereomer mixture of an optically active α-substituted aminoketone. One of the diastereomers is isolated optionally after the diastereomers are converted to salts with an acid. The optically active α-substituted aminoketone or a salt thereof thus isolated was stereoselectively reduced to yield an optically active β-substituted amino alcohol. The optically active β-substituted amino alcohol is subjected to hydrogenolysis to produce an optically active β-amino alcohol or a salt thereof.
