Using <I>cyclo</I>((<I>S</I>)-phenylalanyl-(<I>S</I>)-histidyl) as catalyst, optically active cyanohydrins from substituted benzaldehydes with <I>p</I>-methyl, <I>m</I>-methyl, <I>o</I>-methyl, <I>m</I>-methoxyl, or <I>m</I>-phenoxyl group were obtained with optical yield of 82–33%. For the asymmetric cyanohydrin synthesis, nonpolar solvent such as benzene or carbon tetrachloride was advantageous, while no asymmetric synthesis took place in methanol or dimethyl sulfoxide.
