    Abstract: PROBLEM TO BE SOLVED: To provide a practical process for industrial production of an optically active 3-amino-2-hydroxypropionic acid cyclopropylamide derivative or a salt thereof useful as an intermediate of a medicine from a low cost and easily obtainable raw material, and useful intermediates thereof.SOLUTION: At first, an optically active epoxycarboxylic acid derivative is produced by an asymmetric reduction of an easily available 2-halo-3-oxopropionic acid derivative, followed by epoxidation of the resulting substance. Then, the optically active epoxycarboxylic acid derivative is reacted with cyclopropylamine to convert it into an optically active epoxyamide derivative, which derivative is then reacted with a nitrile to produce an optically active oxazolinamide derivative. Subsequently, an optically active 3-amino-2-hydroxypropionic acid cyclopropylamide derivative or a salt thereof is produced by a selective acid solvolysis of the oxazoline skeleton.
