Article abstract of DOI:10.1246/cl.1991.1787

Reaction of 2,3-epoxy-1-ol methanesulfonates with diethylaluminum chloride or with the mixture of diethylaluminum chloride and diethylamine hydrobromide in dichloromethane gave rise to regioselectively the corresponding 3-chloro- and 3-bromo-1,2-diol 1-methanesulfonates, respectively, in excellent yields.
