Verfahren zur Herstellung von optisch aktiver beta-Halomilchsäure oder Glycidsäure

Optically active beta -halolactic acids can be produced by contacting an alpha , beta -dihalopropionic acid with 2-halo acid dehalogenase. When the pH of the reaction system is above 9, this process gives optically active glycidic acid. Treatment of the optically active beta -halolactic acid thus ob...

Zusammenfassung:Optically active beta -halolactic acids can be produced by contacting an alpha , beta -dihalopropionic acid with 2-halo acid dehalogenase. When the pH of the reaction system is above 9, this process gives optically active glycidic acid. Treatment of the optically active beta -halolactic acid thus obtained with an alkali also gives optically active glycidic acid.
