Stereoselective synthesis of a C-glycoside analogue of N-Fmoc-serine β-N-acetylglucosaminide by ramberg–bäcklund rearrangement

A C-glycoside analogue of N-Fmoc-serine β-N-acetylglucosaminide 1 was synthesized stereoselectively from a sulfone derivative of serinol thio-N-acetylglucosamide 8 using a Ramberg–Bäcklund rearrangement as a key step.
