Chiral Phosphoric Acid-Catalyzed Enantioselective Construction of 2,3-Disubstituted Indolines

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).

Bromination of N,N'-Bis(arylsulfonyl)-1,4-benzoquinonediimines and 1,4-Phenylenediamines

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
