摘要：

An efficient and green procedure has been developed for the synthesis of beta-hydroxy thiocyanate by the regioselective ring opening of epoxides with NH4SCN. The reaction was carried out in water without any organic solvent at 40 degrees C, using Al-MCM-41 (a mesoporous aluminosilicate) as catalyst. In this method, several types of epoxides carrying electron-donating or withdrawing groups were rapidly converted to the corresponding beta-hydroxy thiocyanates in good from excellent yields. Various advantages associated with this protocol include simple workup procedure, short reaction times, high product yields, greater regioselectivity, and easy recovery and reusability of the catalyst.
