Aluminum tris (dodecyl sulfate) trihydrate Al(DS)3·3H2O as an efficient Lewis acid–surfactant-combined catalyst for organic reactions in water: Efficient conversion of epoxides to thiiranes and to amino alcohols at room temperature

High yielding preparation of structurally different thiiranes, β-amino alcohols and bis(β-amino) alcohols from the reaction of epoxides with thiourea and amines in the presence of catalytic amounts of aluminum tris (dodecyl sulfate) trihydrate Al(DS)3·3H2O as a Lewis acid–surfactant-combined catalyst at room temperature in water has been described. Ring opening of epoxides with amines in the presence of this catalyst proceeded with high chemo- and regioselectivity.

All the reactions proceeded smoothly and the isolation of the products was simple and not time consuming process.
