Efficient Copper-Mediated Reactions of Nitrenes Derived from Sulfonimid— The title intermediates are efficiently converted to sulfimides, sulfox02- 037 amides.
imines, and aziridines in good yields. The reaction proceeds through a copper-mediated
multicomponent reaction. It is crucial that sulfonimidates are added together with
iodosobenzene in five small lots (one every 15 min) to a slurry of a nitrene trap. Upon
starting from a chiral enantiopure sulfoxide, reaction proceeds with retention of optical
purity of the sulfoxide sulfur atom. — (LECA, D.; TOUSSAINT, A.; MAREAU, C.;
