Separation and quantitation of enantiomeric 3,6-anhydrogalactoses by conversion to the corresponding diastereomeric acetylated sec-butyl 3,6-anhydrogalactonates
A method to determine the proportion of both enantiomers of 3,6-anhydrogalactose in a sample has been developed using methyl 3,6-anhydro-α-d-galactoside as a model compound. It involves an oxidative hydrolysis to obtain the corresponding aldonic acids, which are further converted to the acetylated d...
