Application

(R)-N-[(1R,2R)-2-(3-(3,5-Bis(trifluoromethyl)phenyl)ureido)cyclohexyl]-tert-butyl-sulfinamide is a sulfinamide-urea based chiral catalyst that can be used to synthesize:
  • Enantioselective homoallylic amines by asymmetric allylation of acylhydrazones with allylindium reagents.
  • Tetrahydroquinolines via an asymmetric Povarov reaction.
  • 2-aryl-substituted cycloalkanones by enantioselective protonation of corresponding trimethylsilyl enol ethers.

The application of chiral sulfinamides and achiral sulfonic acids as a cocatalyst system for enantioselective protonation reactions is described. Structurally simple, easily accessible sulfinamides were found to induce moderate-to-high ee's in the formation of 2-aryl-substituted cycloalkanones from the corresponding trimethylsilyl
