PRODUCTION OF 5-(4'-HYDROXYPHENYL)HYDANTOIN AND D-P-HYDROXYPHENYLGLYCINE FROM 4-HYDROXYACETOPHENONE

摘要

The present invention provides a method for producing an hydroxyaromatic ketoacetal from an hydroxyaromatic methylketone. The invention further provides a method for producing an hydroxyaromatic ketoaldehyde from an hydroxyaromatic ketoacetal. The hydroxyaromatic ketoaldehyde can be further reacted to form a hydantoin, which hydantoin can be hydrolyzed to produce a hydroxyphenylglycine.
