Sažetak
O-Glucosylation of 1-pentanol, 1-octanol, 2-phenylethanol, benzyl alcohol, (±)-2-pentanol and (±)-menthol in 1,4-dioxane, using anhydrous FeCl3, afforded anomeric mixture of the corresponding
glucofuranosides as major and glucopyranosides as minor products in overall yields 20–52 %. Practical advantages of GC-MS for characterizing the prepared acetylated glucofuranosides are in the focus of this paper. Glucofuranoside tetraacetate spectra contain characteristic signals of glucone (acetylated glucose) along with fragments of the aglucone moiety. The mass range was 50–600 mass units and acetyl ion was not present in the spectra, which is of interest
for differentiating glucofuranoside and glucopyranoside tetraacetates.
