The synthesis of highly substituted chiral hydantoins from simple dipeptides proceeded through the dual activation of an amide and a tert-butyloxycarbonyl (Boc) protecting group by Tf2O-pyridine under mild conditions in a single step. This method was successfully applied in the preparation of various biologically active compounds, including drug analogs and natural products.
