Regio- and Stereoselectivity in Glycosylation of Partially Protected 1-Thioglycosides with Glycals

Pastuch G., Wandzik I., Szeja W.

Polish Journal of Chemistry

2007

Vol. 81, nr 2

161-170

We present herein studies of the influence of silyl protecting groups on regio- and stereoselectivity of glycosylation of partially protected (5-nitro-2-pyridyl) 1-thioglycosides with glycals.

Stereoselective Synthesis of (1--6)-alfa-Linked Di- and Trisaccharides, Derivatives of 2-Deoxysugars

Wandzik I., Pastuch-Gawołek G., Szeja W.

Polish Journal of Chemistry

2005

Vol. 79 / nr 10

1681-1687

We present herein the totally stereoselective synthesis of (1--6)-alfa-linked di- and trisaccharides by addition of thioglucosides to D-glucals.

Synthesis of modified oligosaccharide derivatives by Ferrier rearrangement

Wieczorek E., Thiem J.

Polish Journal of Chemistry

1999

vol. 73 nr 7

1111-1121

Various glycols of the hexose and pentose series and different dideoxy hexopyranosides undergo smooth (Lewis) acid -catalyzed allylic rearrangement reactions to regioisometric deoxygenated disaccharide derivatives. The corresponding saturated components were obtained by hydrogenation. In addition, yhe neutral version of the Ferrier reaction employing pentenoyl glucal was tested, which gave rearrangement and addition products. Finally, certain glycols were condensed with differently functionalized glycols as aglyconic components to form disaccharide glycals.
