Asymmetric transfer of nitrenes catalyzed by chiral dirhodium(II) using aromatic sulfamate esters

, p. 1019 - 1026 (2004)
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 [Rh 2{(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 rather than insertion. The intermolecular amidation of indane proceeded with up to 97% yield when the reaction was carried out with the sulfamate in excess.

The design, synthesis and calcimimetic properties of various cyclic sulfonamides and sulfamates are described. The latter were prepared from the corresponding o-alkenylarenesulfonamides via copper- or rhodium-catalyzed intramolecular aziridination. The si
