Unique alkoxysulfonyl aziridine heterocycles were prepared through selective intra- and intermolecular alkeneoxidation reactions. These methods are general and perform efficiently at low Rh-catalyst loadings (1–2 mol %) with only a slight excess of an inexpensive commercial oxidant, PhI(OAc)2. For intermolecular processes, trichloroethylsulfamate was identified as a novel and markedly effective N-atom
