-
Cyclo(L-Phe-L-His) prepared by a modified procedure showed high activity. and enan-tioselectivity in the asymmetric synthesis of aromatic Cyanohydrins from benzaldehyde and m-phenoxybenzaldehyde. The influence of the reaction conditions on the activity and sele-ctivity of the dipeptide has been investigated. The cyclodipeptide can be easily recovered and reused without any loss of the catalytic activity. The optical and chemical stability as well as the relationship between the aggregation and properties of the catalyst have been discussed.
