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