An improved fully stereoselective synthesis of both enantiomers of rimantadine and its trifluoromethylated analogues has been developed, using N-isopropylsulfinylimines as a starting chiral material, proving the superiority of the isopropyl group as a chiral inducer over the tert-butyl group in the case of hindered N-sulfinylimines.
