A solution of methyl-α-L-rhamnopyranoside (1.78 g, 10 mmol) in water (25 ml) was treated with sodium periodate (4.3 g) at 0° C. After 3 hours sodium hydrogen carbonate was cautiously added to neutralize the acid, the mixture was poured into ethanol (100 ml) and the insoluble material was filtered. The filtrate was concentrated to a syrup that was extracted with acetonitrile (15 ml). The extract was used for the next step without further purification.
