Highly regioselective ring opening of epoxides to halohydrins has been carried out in impressive yields with hydrogen and lithium halides in presence of β-cyclodextrin using water as solvent.
α-Hydroxymethylarylketones can be synthesized in good yields from easily accessible epoxides in the presence of β-cyclodextrin and NBS in water. This method is a direct, one-pot, synthesis under mild conditions using water as solvent and has many advantages over existing methodologies.
