- Process for preparing compositions containing neotrehalose
-
Neotrehalose is prepared in a relatively high-yield by a process comprising allowing β-galactosidase to act on a solution containing lactoneotrehalose to form neotrehalose and recoverying the resultant neotrehalose. The neotrehalose is a non-reducing oligosaccharide having a satisfiable stability and a rich- and high-quality-sweetness and is assimilated and utilized as energy source in vivo when orally administered. Neotrehalose in the form of crystal has a satisfiable handleability because it is readily soluble in water and substantially free of hygroscopicity. These render neotrehalose very useful in the fields of food-, cosmetic- and pharmaceutical-industries.

- SYNTHESIS OF UNSYMMETRICAL TREHALOSE ANALOGUES BY SILVER TRIFLUOROMETHANESULPHONATE PROMOTED GLYCOSYLATIONS
-
The coupling of benzoylated glucosyl bromides with 2,3,4,6-tetra-O-benzylated gluco, manno or galacto-pyranoses promoted by silver triflate is described, and the compositions of the crude reaction mixtures, determined by 13C NMR spectroscopy, are presente

- Synthesis and glycosylation shift of 1,1'-disaccharides
-
Nineteen kinds of nonreducing 1,1'-disaccharides have synthesized by modified Koenigs-Knorr method, and characterized by NMR. The glycosylation shift of each anomeric carbon has been estimated.
