HSCN condensation with ulosides: preferred formation of carbohydrate-fused hemiaminals of the 4-hydroxy-1,3-oxazolidine-2-thione type

Selected ulofuranosides and ulopyranosides react with thiocyanic acid to give good yields of stable carbohydrate-fused hemiaminal 1,3-oxazolidine-2-thiones.

DDQ-mediated regioselective de-O-benzylation of pyranosides stilted by a 4,6-O-(2-phenylsulfonyl)ethylidene (PSE) clip

A model study on diverse 4,6-acetalated O-benzylated D-glucopyranosides was performed to evaluate DDQ-mediated regioselective de-O-benzylation in connection with structural rigidity.

Phenylsulfonylethylidene (PSE) acetals: A novel protective group in carbohydrate chemistry

A range of sugar-derived phenylsulfonylethylidene acetals were easily obtained from the corresponding diols and 1,2-bis(phenylsulfonyl)ethylene under basic conditions. Deprotection methods for such acetals have also been investigated.

Phenylsulfonylethylidene (PSE) acetals as atypical carbohydrate- protective groups

We introduce a new class of arylsulfonylated cyclic acetals derived from carbohydrate structures which are synthesized with high yields under basic conditions. Deprotection methods for such acetals are also investigated. (C) 2000 Elsevier Science Ltd.
