be a suitable glycosylating agent for the acid-catalysed, directsynthesis of O-, S- and N-glucofuranosyl compounds. Beta-linked products are formed with good selectivity. Reaction with cyanotrimethylsilane gave the 1,2-O-(1-cyanopropylidene)acetal rather than the C-glycosyl cyanide. By selective acid-catalysed hydrolysis, the title compound was converted to the 1-hydroxy analogue from which the trichloroacetimidates
A &bgr;-D-glucofuranose compound which is 1,2,3,5,6-penta-O-propanoyl-&bgr;-D-glucofuranose, preferably in crystalline form, is prepared from D-glucose. The compound is prepared by reacting D-glucose with boric acid, or an equivalent thereof, followed by treatment with a propanoylating reagent, preferably propanoic anhydride. The compound is useful for the preparation of other compounds, such as glucofuranosides.
We describe a method of growing an animal cell in a culture medium, in which the culture medium comprises an elevated concentration of a thymidine family member, in which the growth or viability of the animal cell is increased as a result of the elevated concentration of the thymidine family member in the cell culture medium. Preferably, the cell culture medium comprises a semi-solid medium, which is a serum free or chemically defined medium.
