Synthetic studies of moenomycin a disaccharide analogues. Protection of the anomeric centre with long-chain protective groups

Article abstract of DOI:10.1016/S0040-4020(98)01062-X

Two new C₉ protecting groups for the anomeric position of carbohydrates are reported. Methods both for their introduction and removal are described. The C₉-protected compounds are much less polar than the corresponding allyl protected analogues. The new protecting group chemistry has been used to prepare compound 17 en route to a disaccharide analogue of the antibiotic moenomycin A.
