The use of imines, including those derived from amino esters, as selective nucleophilic trapping agents for thiiranium ions generated in situ from 2,3-epoxy sulfides under Lewis acidic conditions, is reported. The initially formed iminium ions are readily hydrolysed by aqueous base to liberate a secondary amine, the product of overall selective monoalkylation of a primary amine.
