• Optical activation of 2-phenylpropionaldehyde (PPA) <I>via</I> enamines using L-proline derivatives as amine components was studied. <I>S</I>(+)-PPA was obtained when <I>R</I>(−)-2-methylpyrrolidine and <I>S</I>(−)-2-ethoxycarbonylpyrrolidine were used, while <I>R</I>(−)-PPA was obtained when <I>S</I>(−)-prolinamide, <I>N</I>-(L-prolyl)pyrrolidine, <I>N</I>-(L-prolyl)piperidine, <I>S</I>(+)-2-(1-pyrrolidinylmethyl)pyrrolidine, and <I>S</I>(+)-2-(piperidinomethyl)pyrrolidine were used. This suggests that there are two mechanisms for optical activation.
