Enantioselective intra-and intermolecular insertions of aromatic sulfamate esters into activated C–H bonds have been achieved via in situ generated phenyliodinanes in the presence of PhI (OAc) 2, MgO, and chiral Rh (II) catalysts. The optimal results were obtained with [Rh2 {(S)-nttl} 4] and [Rh2 {(R)-ntv} 4] as catalysts with up to 52% ee. In contrast, phenylsulfamates with allylic ortho-substituents reacted via intramolecular aziridination ...
