Synthesis of various carbonyl derivatives
An oxo-amination process with readily available N-bromosuccinimide (NBS) and secondary amines as N-sources and dimethyl sulfoxide (DMSO) as the oxidant provides amino alcohols in a single step. For the first time, the formation of reactive Me2S+-O-Br species generated by the interaction of NBS with DMSO has been proven.

IBX has been utilized for the oxidation of various epoxides and aziridines as their β-cyclodextrin complexes in water to afford α-hydroxyketones and α-aminoketones in good yields, respectively.
