A highly regioselective method for the synthesis of beta-iodohydrins and beta-bromohydrins by the direct ring opening of epoxides with elemental halogen in the presence of thiourea is described. This method occurs under neutral and mild conditions with high yields in various solvents even when sensitive functional groups are present. (C) 2003 Published by Elsevier Ltd.

The highly regioselective method for the synthesis of β-iodohydrins and β-bromohydrins by the direct ring opening of 1,2-epoxides with elemental halogen in the presence of phenylhydrazine is described. This method occurs under neutral and mild conditions with high yields in various aprotic solvents even when sensitive functional groups are present.
