Zusammenfassung:FIELD: chemistry; pharmacology. ^ SUBSTANCE: invention refers to method of 6-O-[beta-D-(2,3,4,6-tetra-O-acetyl)glucopyranosyl]-d,1-alpha-tocopherol (1) or 6-O-[beta-D-(2,3,4,6-tetra-O- acetyl)galactopyranosyl]-d,1-alpha-tocopherol (2), consisting in interaction of alpha-tocopherol and alpha- or beta-anomer of related D-gluco- or D-galactopyranose pentaacetates with added catalyst systems: BF3.OEt2 ionic liquid [bmim]PF6 at mole ratio alpha-tocopherol:sugar pentaacetate: BF3.OEt2:[bmim]PF6 = 1:1:2.5:0.3-5, in methylene chloride within 3 h at room temperature. ^ EFFECT: given compounds are precursors of related deacetylated glycosides with observed antiallergic and anti-inflammatory activity. ^ 1 cl, 8 ex
