Gj. Boons et al., CHEMOSELECTIVE GLYCOSYLATIONS .1. DIFFERENCES IN SIZE OF ANOMERIC LEAVING GROUPS CAN BE EXPLOITED IN CHEMOSELECTIVE GLYCOSYLATIONS, Tetrahedron letters, 36(35), 1995, pp. 6325-6328
We have developed a novel chemoselective glycosylation strategy. This
glycosylation strategy is based on the fact that the glycosyl reactivi
ty of an anomeric thiol group can 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 oligosacchar
ides of biological importance to be prepared in a highly convergent ma
nner.
