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