Under basic conditions, 2-aldehydo (acetonyl) 2-O-Ms(Ts)-α-C-glycosides undergo an intramolecular SN2 reaction to form 1,2-cyclopropanated sugars, which react with nucleophiles (alcohols, thiols, and azide) at the anomeric carbon to give 2-C-branched glycosides. By way of contrast, the 1,2-cyclopropanes derived from 2-ketones only react with thiols to give 2-C-branched thioglycosides. |
