The regioselective ring-opening of 1,2- and 1,3-sulfamidates with fluorine anion is reported. Construction of monofluoro-substituted amines and amino acid derivatives is realized by using inexpensive potassium fluoride (KF). The monofluorination process only needs 35 minutes under heating, which will be an attractive new route for the synthesis of the PET fluorine-18 radiotracer.
