Abstract
Condensation of 4-nitrophenylthioD-glycosyl acceptors with ethylthioD-glycosyl donors in the presence of thiophilic promoters IDCP and NIS/TfOH, according to the “latent-active” principle proposed by Royet al, did not proceed in all cases as expected. On the other hand, replacement of the ethylthio function by an n-pentenyloxy group shows promise for the future chemoselective assembly of oligosaccharides.
