DIBROMINATION OF BENZYLOXY-GROUPS: GLYCOSYL BROMIDES FROM BENZYL GLYCOSIDES

Collins, P. M.,Premaratne, P.,Manro, A.,Hussain, A.

, p. 4721 - 4722 (2007/10/02)

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.
