Reported is the first stereoselective method for β-xylulofuranosylation, which employs 3,4-O-xylylene-protected thioglycoside donors. For most acceptors, the best results were observed with a donor (8) that possesses both the xylylene group and a benzoate ester at O-1. To demonstrate its utility, the methodology was applied to the first synthesis of the pentasaccharide repeating unit from the lipopolysaccharide O-Antigen of Yersinia enterocolitica serovars O:5/O:5,27, a structure containing two β-xylulofuranose residues.
β-selective arabinofuranosylation using a 2,3-o-xylylene-protected donor

Reported is a novel stereoselective β-arabinofuranosylation that makes use of a conformationally restricted 2,3-O-xylylene-protected arabinofuranosyl donor. Optimization of the reaction conditions showed that factors including the structure of the accepto
Stereoselective synthesis of a fragment of mycobacterial arabinan

Strategies for the stereoselective synthesis of mycobacterial arabinan were explored. Arabinofuranosyl donors with various protective groups were screened in terms of suitability for β-(1,2-cis)-selective glycosylation. The protective group was found to affect the stereoselectivity of arabinofuranosylation. β-Selectivity was drastically enhanced by using donors protected with 3,5-TIDPS, possibly due to conformational constraints on the furanose ring. Synthesis of heptaarabinofuranoside was then performed to demonstrate the practicality of this methodology.
