Abstract
The stereodefined construction of quaternary pseudoanomeric centers by way of a BF3·Et2O-catalyzed, Fries-type rearrangement of O-ketosides is described. This method provides new access to C-naphthyl ketosides related to biologically relevant products with good to complete stereocontrol in favor of the β product.
