Article abstract of DOI:10.1021/jo00298a002

A mild procedure to obtain halo diols by opening epoxy alcohols with halogen is described.The method is based on the use of Ti(O-i-Pr)4 and the suitable halogen over allylic and homoallylic epoxy alcohols, affording high regioselectivities and yields.Reaction with enantiomerically enriched epoxides leads selectively to chiral halohydrins.
