Stereoelectronic Effects Determine Oxa-carbenium vs β-Sulfonium Ion Mediated Glycosylations
[Image: see text] Activation of a glycosyl donor protected with a 2-O-(S)-(phenylthiomethyl)benzyl ether chiral auxiliary results in the formation of an anomeric β-sulfonium ion, which can be displaced with sugar alcohols to give corresponding α-glycosides. Sufficient deactivation of such glycosyl d...
