Abstract

A convenient route to Se-S-glycoside derivatives was developed using glycosyl isoselenuronium salts as glycosylselenenyl transfer reagents toward thiols. Aliphatic and aromatic thiols were found to react in the presence of N,N-diisopropylethylamine as a base and furnished alkyl- or aryl glycosylselenenylsulfide derivatives. S-glycosylselenenyl-cysteines were obtained similarly via reactions with O,N-protected cysteine. Reactions with monosaccharide thiols provided disaccharide mimics featuring Se-S- interglycosidic bonds. Further disaccharide mimics with Se-Se interglycosidic linkage were obtained from the starting isoselenuronium salts via reactions with protected monosaccharide derivatives bearing selenol groups in 6- or 4-position. The novel glycomimetics are expected to open new perspectives in biological activities and/or mechanistic studies due, i.a., to the rather uncommon Se-S- or Se-Se bonds incorporated into a carbohydrate framework.
