• The catalytic activity of (5<I>R</I>)-5-(4-imidazolylmethyl)-2,4-imidazolidinedione (<B>3</B>) was examined in the asymmetric hydrocyanation of 3-phenoxybenzaldehyde (<B>1a</B>) to (<I>S</I>)-2-hydroxy-2-(3-phenoxyphenyl)acetonitrile ((<I>S</I>)-<B>2a</B>), an important alcohol moiety of optically active pyrethroid insecticides. Among the catalysts, 3-benzyl derivative (<B>3d</B>) exhibited moderate enantioselectivities for <B>1a</B> and other benzaldehydes.
