Abstract: Process for the preparation of homogentisic lactone by reacting hydroquinone with a di(lower alkyl) chloro (or bromo) malonate and an alkali metal lower alkoxide to give an alkali metal 3-carbo(loweralkoxy)-5-hydroxy-2-oxidobenzo[b]furan which is subsequently decarboxylated by treatment with a strong mineral acid to give homogentisic lactone. The latter is readily converted into homogentisic acid by conventional means.
