Highly enantio- and regioselective (3 + 2) formal cycloaddition of β-substituted ene- and thioenecarbamates as well as cyclic enamides with quinone diimides catalyzed by a BINOL- and SPINOL-derived phosphoric acid is reported. A wide variety of 2,3-disubstituted 2-aminoindolines, including polycyclic ones, were prepared in generally high yields (up to 98%) with moderate to complete diastereoselectivities and in most cases excellent enantioselectivities (up to 99% ee).

Abstract: Reactions of (chlorosulfanyl)benzenes with benzene-1,4-diamines afforded new N,N′-bis(arylsul-fanyl)cyclohexa-2,5-diene-1,4-diimines which were oxidized to N,N′-(cyclohexa-2,5-diene-1,4-diylidene)-bis(arenesulfinamides) with 2 equiv of m-chloroperoxybenzoic acid. When the oxidation was carried out using 4 equiv of m-chloroperoxybenzoic acid, the corresponding bis-sulfonamides were obtained. The synthesized compounds were predicted in silico to exhibit biological activity with a high probability.

Depending on the solvent, molar reactant ratio, and other conditions, bromination of N,N'-bis(arylsulfonyl)-1,4-benzoquinonediimines and N,N'-bis(arylsulfonyl)-1,4-phenylenediamines yields 1,4-bis(arylsulfonylimino)-5,6-dibromo-2-cyclohexenes, N,N'-bis(ar

The chlorination of N,N'-bisarylsulfonyl-1,4-phenylenediamines leads to 1,4-bisarylsulfonylimino-2,3,5,5,6,6-hexachloro-2-cyclohexenes.Together with the chlorination products chloranil and/or 2,3,5,5,6,6-hexachloro-1,2-cyclohexene-1,4-dione were isolated as a result of the competing hydrolysis process.
