The enantioselective photoreduction of the helical substrates of rac- (acac- = acetylacetonato) and rac-^- (edta^4- = ethylenediaminetetraacetato) with the newly synthesized helical photocatalysts Δ- (or rac)-2+ -2,2'-bipyridine>, and Λ- (or Δ)-3>²⁺ <(S or R)-PhEtbpy = 4,4'-bis<(S)-(-) or (R)-(+)-1-phenylethylaminocarbonyl>-2,2'-bipyridine> was realized in the helical-shape recognition reaction with a maximum enantiomer rate ratio (k^Δ/k^Λ) of 14.7 in 90percent v/v EtOH-H2O at 25 degC.
