The preparation of a stabilized monofluorobenzyl carbanion by means of a remote homochiral sulfinyl group and its completely stereoselective reactions with N ‐ p ‐tolylsulfinylimines are described. The use of these reactions followed by the simultaneous removal of both chiral auxiliaries with t BuLi, which occurs without epimerization at the benzylic position, provides the quickest entry to enantiomerically pure β‐fluorinated β‐phenylethylamines.
