An interesting example of neighboring-group participation is the formation of di-0-acetyl-l,4-anhydro-a-L-rhamnopyranose (XLIV) on reaction of a-aceto-L-rhamnosyl bromide (XLIII) with trimethylamine in... 

The seroreactivity of a synthetic monoglycosyl NGC related to the major phenolic glycolipid of M. bovis BCG has provided strong confirmatory evidence for revision of the enantiomeric configuration of the glycosyl residue in the so-called mycoside B 78 to that of 2-O-methyl-a-L-rhamnopyranose. The NGC with the glycosyloxynonanoyl linker-arm was suitable for the serodiagnosis of bovine tuberculosis.

Simple one-pot synthesis of different 1-0-glycosylboranophosphate diesters (65), the stable analogues of 1-0-glycosylphosphates based on the anomeric H-phosphonate of a-L-rhamnopyranose as common precursor, has been reported. Various phosphodisaccharides, structural analogues of phosphate (66) including deoxy, fluoro and aminodeoxy disaccharide phosphates e.g. (67) have been synthesized. These phosphodisaccharides were tested as acceptor sub-strate/putative inhibitors for the Leishmania-a-D-mannosylphosphate transferase. 

The only carbohydrate derivatives incorporating V-thiocarbonyl functional groups of natural origin appear to be isothiocyanate and thiocarba-mate glycosides embodying a-L-rhamnopyranose and 4-hydroxybenzyl...
