Bromination of 1,5-anhydrohex-1-enitols (glycals) using quaternary ammonium tribromides as bromine donors: Synthesis of α-1,2-trans-2-bromo-2-deoxyglycopyranosyl bromides and fluorides

Addition of bromine to glycals using quaternary ammonium tribromides as bromine donors is realized with higher stereoselectivities (α-1,2-trans configurated products) compared to bromination with molecular bromine. The reaction is neither sensitive to the
