Chiral sulfoximines with stereogenic sulfur atoms are promising motifs in drug discovery. We report an efficient method to access chiral sulfoximines through a C−H functionalization based kinetic resolution. A rhodium(III) complex equipped with a chiral Cpx ligand selectively participates in conjunction with phthaloyl phenylalanine in the C−H activation of just one of the two sulfoximine enantiomers...
Sulfoximines with stereogenic sulfur atoms are attractive structural motifs in drug discovery. A direct catalytic enantioselective method for the synthesis of sulfur‐chiral 1,2‐benzothiazines from readily accessible diaryl sulfoximines is presented. Rhodium(III) complexes equipped with chiral cyclopentadienyl ligands and paired with suitable carboxylic acid additives engage in an enantiodetermining...
