摘要：

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 → β; 2-FManno/pivaloyl → α) leading to fluoro-glycostructures with excellent control over the anomeric configuration. © 2010 WILEY-VCH Verlag GmbH & Co.
