We have developed a novel chemoselectiveglycosylation strategy. This glycosylation strategy is based on the fact that the glycosyl reactivity of an anomeric thiol groupcan be control by the bulkiness of this group whereby we have produced a new range of differentially reactive coupling substrates. The new approach will enable complex oligosaccharides of biological importance to be prepared in a highly

We have developed a novel chemoselectiveglycosylation strategy. This glycosylation strategy is based on the fact that the glycosyl reactivity of an anomeric thiol groupcan be controlled by the bulkiness of this group whereby we have produced a new range of differentially reactive coupling substrates. It was also shown that the anomeric configuration of the thioglycosides affects the reactivity of
