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

This invention relates to compositions and methods for achieving the efficient aziridination of organic molecules, especially olefins. More specifically, the invention is directed to a mild, selective, and efficient aziridination protocol that involves catalysis by a mixed-valent dirhodium(II,III) catalyst (Rh25+). Especially preferred sources for forming such mixed-valent dirhodium(II,III) catalyst (Rh25+) are dirhodium(II) carboxamidates, such as dirhodium(II) caprolactamate, and their derivatives and analogues.
Synthesis of cyclic sulfonamides via intramolecular copper-catalyzed reaction of unsaturated iminoiodinanes
Dauban, Philippe,Dodd, Robert H.
, p. 2327 - 2329 (2007/10/03)
(equation presented) Olefinic primary sulfonamides were treated with iodebenzene diacetate and potassium hydroxide in methanol to give intermediate iminoiodinanes. Catalytic copper(I) or (II) triflate then provided intramolecular nitrene delivery leading to aziridene formation except in one case where a rare copper-catalyzed C-H insertion was observed. The aziridines could be opened by various nucleophiles (methanol, thiophenol, allylmagnesium bromide, benzylamine) to give the corresponding substituted cyclic sulfonamides.
