DIBROMINATION OF BENZYLOXY-GROUPS: GLYCOSYL BROMIDES FROM BENZYL GLYCOSIDES

Article abstract of DOI:10.1016/S0040-4039(01)80784-X

Bromination of benzyloxy groups in sugar derivatives with bromotrichloromethane and ultraviolet light rapidly gives α-bromobenzyloxy sugars.On further irradiation α,α-dibromobenzyloxy derivatives are formed from benzyl sugar ethers, whereas glycosyl bromides are produced from benzyl furanosides and pyranosides.
