Oxidative C-H amination of chiral sulfamate esters using achiral Rh-carboxylate catalysts, PhI(OAc)(2), and MgO occurs in high yield and with good to excellent diastereocontrol. A number of examples are included to support a proposed transition state model that accounts for the observed stereoinduction. In addition, stereoselective intramolecular aziridination with substituted homoallyl sulfamates is demonstrated and is rationalized through an analogous stereochemical construct. [reaction: see text]
