Everything’s under control: A stabilizing fluorine electrostatic interaction has been exploited to control oxonium ion conformation in 2-fluoropyranose derivatives (see scheme). When matched with the inductive nature of the protecting groups, the glycosyl donors were found to be highly selective (2-FGluc/benzyl ? beta; 2-FManno/pivaloyl ? alpha) leading to fluoro-glycostructures with excellent control over the anomeric configuration.

The glycosyl trichloroacetimidates 1-alpha,beta, 8-alpha, 11-alpha, 13-alpha, 15-alpha, and 17-alpha directly transfer the glycosyl moiety to phosphoric acid mono- and diesters.The acidity of the phosphoric acid derivatives used was sufficient for the activation of the trichloroacetimidates, therefore an additional acidic catalyst was not required.From the beta-imidate 1-beta alpha-glycosyl phosphate and from the alpha-imidates preferentially beta-glycosyl phosphates were obtained.Reaction of dibenzyl phosphate (2a) and cetyl phosphate (2c) with 1-alpha demonstrated that beta/alpha-anomerization iscatalyzed by traces of acid.The glycosyl phosphates 3a-alpha, 3a-beta – 3c-beta, 3f-alpha, 9a-beta, and 9c-beta were partly or totally deprotected.The structures of the synthezised compounds were assigned by 1H NMR spectroscopy and by comparison with literature data.
