Several benzaldoximes, benzaldehyde-O-ethyloximes, and acetophenonoximes were synthesized and evaluated as tyrosinase inhibitors by an assay based on tyrosinase catalyzed L-DOPA oxidation. Whereas benzaldoxime itself is only a weak inhibitor, its derivatives with one or two hydroxy or methoxy moieties in para and meta positions depress tyrosinase activity. Acetophenonoximes and trisubstituted benzaldoximes
Catalytic dehydration of aldoximes can be performed efficiently with NiCl2 in acetonitrile under neutral and mild conditions. Under these conditions, various functionalized aldoximes produce the corresponding nitriles in good to excellent yields.
