Efficient intramolecular β-mannoside formation using m-xylylene and isophthaloyl derivatives as rigid spacers
Abdel-Rahman, Adel A.-H.,El Ashry, El Sayed H.,Schmidt, Richard R.
, p. 195 - 206 (2007/10/03)
A series of mannosyl donors linked via position 2 to an m-xylylene or an isophthaloyl spacer which was connected to the position 6 of a glucoside acceptor afforded, via intramolecular glycosylation, the corresponding disaccharides with high β anomeric ratio.

Pyrimidin-2-yl 2,3,4,6-tetra-O-benzyl-1-thio-α-D-mannopyrano side (9), pyrimidin-2-yl 2,3,4-tri-O-benzyl-α-L-rhamnopyranoside (10), pyrimidin-2-yl 2-O-acetyl-3,4,6-tri-O-benzyl-1-thio-α-D-mannopyranoside (7), and pyrimidin-2-yl 2-O-acetyl-3,4-di-O-benzyl-1-thio-α-L-rhamnopyranoside (8) were prepared almost quantitatively from the corresponding protected 1,2-O-methoxyethylidene-β-D-manno-or-β-L-rhamnopyranose with 2-mercaptopyrimidine in the presence of mercuric bromide. Coupling reactions of the thioglycosides promoted by silver triflate with suitable glycosyl acceptors afforded 1,2-trans linked disaccharides. Copyright (C) 1998 Elsevier Science Ltd.
1,2-cis-c-glycoside synthesis by samarium diiodide-promoted radical cyclizations
Skrydstrup, Troels,Mazeas, Daniel,Elmouchir, Mohamed,Doisneau, Gilles,Riche, Claude,Chiaroni, Angele,Beau, Jean-Marie
, p. 1342 - 1356 (2007/10/03)
The samarium diiodide reduction of glycosyl pyridyl sulfones bearing a silicon-tethered unsaturated group at the C2-OH position leads to the stereo-specific synthesis of 1,2-cis-C-glycosides in good yield after desilylation. These reactions proceed via an
