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