Abstract:	The chiral dirhodium(II) carboxylate-catalyzed enantioselective intramolecular C-H amidation reaction of sulfamate esters via in situ generated iminoiodinanes is described. The use of dirhodium(II) tetrakis[N-tetrafluorophthaloyl-(S)-tert-leucinate], Rh2(S-TFPTTL)4, as a catalyst and PhI(OAc)2 as an oxidant provides cyclic sulfamidates in up to 48% ee.
