One-Pot Synthesis of beta-Amino/beta-Hydroxy Selenides and Sulfides from Aziridines and Epoxides

Diaryl disulfides and diselenides undergo facile cleavage on treatment with rongalite (sodium hydroxymethanesulfinate) to generate the corresponding thiolate and selenolate species in Situ, which effect the ring opening of aziridines and epoxides in a regioselective manner. A simple, mild, cost-effective protocol has been developed to prepare beta-amino and beta-hydroxy sulfides and selenides in a one-pot operation.
