Direct gas-chromatographic resolution of dl-myo-inositol 1-phosphate and other sugar enantiomers as simple derivatives on a chiral capillary column☆

Add time:09/24/2019    Source:sciencedirect.com

A commercially available, chiral stationary-phase was used to separate sugar enantiomers. Derivatives commonly used for the gas chromatography of carbohydrates were employed. The most generally useful was found to be the per(heptafluorobutanoyl) derivative, in which form d- and l-arabinose, fucose, xylose, mannose, and chiro-inositol were well resolved. The d and l enantiomers of glucose were best separated as 6-O-trimethylsilyl-α-glucofuranose 1,2:3,5-bis(methaneboronate). dl-myo-Inositol 1-phosphate was well resolved as the 2,3,4,5,6-penta-O-(trimethylsilyl)-1-dimethylphosphate. Other derivatives were less well resolved, and some sugar enantiomers could not be separated by the means used.
