Abstract
A practical synthetic path for the preparation of trans-CF3SF4-substituted amines has been described. Primary and secondary amines bearing a variety of different functional groups including amino acids, cyclic amines, and nucleosides were prepared. The desired amines were synthesized under mild conditions. The influence of the CF3SF4-group on the pKa and log D of a standard amine was established. The unusual conformation of the trans-CF3SF4-substituted tosylate has been verified via its crystal structure.
