By visible-light photoredox catalysis with copper complexes, sulfoximidoyl chlorides add to terminal aryl alkynes to give the corresponding (E)-β-chlorovinyl sulfoximines with exclusive regio- and stereoselectivities in high yields. Two representative pro

Under visible light, N-tosyl-protected sulfoximidoyl chlorides react with aryl alkynes to give β-keto sulfoximines. The reaction is characterized by a high functional group tolerance and good yields. It can be improved by the presence of a ruthenium photo

Sulfonimidamides were prepared in a one-pot transformation from sulfonamides, through nucleophilic substitution of sulfonimidoyl chlorides formed in situ with different amines. This methodology represents a convenient, safe, and easily accessible synthetic route to sulfonimidamides.

N-Protected trifluoromethyl-substituted sulfoximines have been prepared by treatment of sulfonimidoyl fluorides with a combination of the Ruppert-Prakash reagent (TMSCF3) and tetrabutyl ammonium fluoride (TBAF). The starting materials were accessed following two synthetic routes, and for each reaction sequence the substrate scope was evaluated. Accordingly, a wide variety of aryl-substituted products were obtained in moderate to good yield.

(Chemical Equation Presented) Successful matchmaking: The combination of a chiral nitrene precursor with a chiral rhodium(II) catalyst is the key factor that allows efficient intermolecular regioselective C-H amination. Good-to-excellent yields and excellent diastereoselectivities can be obtained with a stoichiometric amount of the C-H bond containing substrate. nttl = N-1,8-naphthoyl-tert-leucine.
Diastereoselective rhodium-catalyzed nitrene transfer starting from chiral sulfonimidamide-derived iminoiodanes

The dirhodium-catalyzed aziridination of olefins with chiral sulfonimidamides as iminoiodane precursors has been investigated under stoichiometric conditions. Diastereoisomeric excesses of up to 82% have been achieved using [Rh2{(S)-nttl}4
Sulfonimidamides: Efficient chiral iminoiodane precursors for diastereoselective copper-catalyzed aziridination of olefins

(Chemical equation presented) N-(p-Toluenesulfonyl)-p- toluenesulfonimidamide reacts with iodosylbenzene to afford in situ a chiral iminoiodane. The latter gives, in the presence of a copper(I) catalyst, a nitrene that is very efficiently transferred unde
