Sixteen methyl glucopyranosyl glucopyranoside disaccharides (methyl β-D-Glcp(p-Br-Bz)-(1→x)-β/ α-D-Glcp) containing β-glycosidic linkages (1→2, 1→3, 1→4, and 1→6) were synthesized and analyzed by means of CD and NMR spectroscopy in three different solvent

Venturello's phosphotungstate complex and titanium(IV) isopropoxide [Ti(O-i-Pr)4] were successfully used as catalysts for the epoxidation-alcoholysis of glycals using hydrogen peroxide [H2O 2]. Reaction substrates included a range of variously protected glycals and different alcohols were used as solvents. Ti(O-i-Pr)4 was only effective in methanol as solvent, but gave methyl glycosides in high yields and high selectivities. The Venturello complex proved to be a very versatile and efficient catalyst. Apart from epoxidation-alcoholysis in alcoholic solvents it also showed activity in biphasic conditions to allow for glycosylation of long-chain alcohols and was very effective in the stereoselective dihydroxylation of benzylated glucal.
Binding studies on internal immunodeterminants: synthesis of β-(1->6)-linked oligosaccharide methyl glycosides having one to four internal D-galactopyranosyl residues flanked by gentiobiose residues

The oligosaccharide glycosides β-D-Glcp-(1->6)-β-D-Glcp-(1->6)-6)>n-β-D-Glcp-(1->6)-β-D-Glcp-1->OMe (n=1-4) were prepared by a convergent block synthesis.Haloacetyl, tert-butyldiphenylsilyl, and dimethylthexylsilyl groups were used as tempo
