aliphatic sulfamates and related derivatives incorporating cyclic/polycyclic (steroidal) moieties in their molecules has been synthesized and assayed as inhibitors of the zinc enzyme carbonic anhydrase (CA) and, more precisely, of the cytosolic isozymes CA I and II and the transmembrane, tumor-associated isozyme CA IX. The most potent CA I inhibitor was n-tetradecyl sulfamate and some (substituted)benzyl/phenethyl
The chiraldirhodium(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], Rh 2 (S-TFPTTL) 4 , as a catalyst and PhI(OAc) 2 as an oxidant provides cyclic sulfamidates in up to 48% ee.
