A facile synthesis of 1,2-azidoalcohols from their epoxides using α,α',α''-N-hexakis(triethylammoniummethylene chloride)-melamine as amulti-site phase-transfer catalyst in water was developed. By this eco-friendly and highly atom-economic method, a variety of 1,2-azidoalcohols was obtained in high yields with excellent regioselectivity and in short reaction times. Application of this six-site PTC in the ring opening of epoxides by cyanide, acetate and chloride anions was also studied. The catalyst can be recovered after completion of the reaction and can be recycled without affecting the catalytic property.
