New Results in the gas chromatographic separation of enantiomers of hydroxy acids and carbohydrates

New chiral stationary phases for the gas chromatographic separation of the enantiomers of amines, amino alcohols, hydroxy acids and carbohydrates are described. Hydroxy acids can be separated on stationary phases prepared from S-2-hydroxyisopentanoic acid and S-2-hydroxyoctanoic acid by coupling wit...

Description
Summary:New chiral stationary phases for the gas chromatographic separation of the enantiomers of amines, amino alcohols, hydroxy acids and carbohydrates are described. Hydroxy acids can be separated on stationary phases prepared from S-2-hydroxyisopentanoic acid and S-2-hydroxyoctanoic acid by coupling with S-phenylethylamine. For the first time the separation of carbohydrate enantiomers could be achieved on a stationary phase obtained by connecting l-valine- S-phenylethylamide to the functionalized cyanoethyl side-chains of the polysiloxane XE-60.
