Thanks for the reply Dan!
I know how to separate enantiomers, by converting them to diasterisomeric salts using a resolving agent, however I'm struggling to deduce how to separate anomers.
An example of the purification step of a particular oligosaccharide:
"The reaction was quenched after 2 h into a separating funnel containing a mixture of DCM (200 mL), saturated aqueous NaHCO3 (200 mL) and Na2S2O3 (10 mL, 10% aqueous). After shaking until the iodine colour was removed the suspension was filtered through a short pad of Celite® washing with water and DCM. The layers were separated and the aqueous extracted with DCM (50 mL). The organic layers were combined, dried (MgSO4) and solvent removed in vacuo. The crude product was purified by silica gel flash column chromatography (EtOAc/hexane 3:7) to give 7 (4.45 g, 88%) as a white foam."
As far as I'm aware, they're not using a resolving agent, so I am unsure as to how they managed to separate the anomers?
