ABSTRACT:
The invention relates to a novel method for preparing pyrocatecholic compounds from monophenolic compounds using catalysis by monophenol monooxygenase in an aqueous solution containing metal ions. The metal ions form complexes with the pyrocatecholic products. This method increases the yield of pyrocatecholic products. In particular, the method of the instant invention can be used to increase the yield of L-DOPA, a drug used in the treatment of Parkinson's disease.
