[GRAPHICS]Hydride reduction of C=N bonds stereocontrolled by intramolecular m-stacking interactions of 1-naphthylsulfinyl and N-aryl groups, nonoxidative Pummerer rearrangement, and ring-closing metathesis are efficiently combined in a highly stereoselective entry to enantiomerically pure cyclic and acyclic fluorinated beta -amino alcohols and alpha -amino acid derivatives, respectively.
