A new stereospecific method for 1,2-cis-glycosylation

A new stereospecific method for 1,2-cis-glycosylation involves the reaction of 1,2-trans-glycosyl thiocyanates with sugar trityl ethers in the presence of triphenylmethylium perchlorate.The method has been applied to give disaccharide derivatives with (1->6), (1->4), (1->3), and (1->2) linkages.

Derivatives of methyl beta-lactoside as substrates for and inhibitors of beta-D-galactosidase from E. coli.

The 2'-,4'-, and 6'-deoxy derivatives of methyl beta-lactoside have been synthesised by deoxygenation at positions 2', 4', and 6', and the 3'-deoxy derivative was obtained by a glycosylation reaction. The 2'-O-methyl, 2'-O-benzyl, 2'-amino-2'-deoxy, and 1

NOVEL HIGHLY STEREOSPECIFIC METHOD OF 1,2-CIS-GLYCOSYLATION. SYNTHESIS OF α-D-GLUCOSYL-D-GLUCOSES

Triphenylmethylium perchlorate-catalysed glycosylation of 2-, 3-, 4-, and 6-O-trityl-D-glucose derivatives with β-D-glucopyranosyl thiocyanates bearing a nonparticipating substituent at O-2 affords stereospecific derivatives of α-D-glucosyl-D-glucose
