6-Fluoro-4-chromanone can be regenerated from (R)-6-fluoro-4-ureidochroman-4-carboxylic acid, or from mixtures of (R)-6-fluoro-4-ureidochroman-4-carboxylic acid and its racemic modification, by oxidation with a permaganate, especially potassium permanganate. 6-Fluoro-4- chromanone is a chemical intermediate useful for preparing sorbinil, an aldose reductase inhibitor which can be used in clinical medicine for the control of the chronic complications of diabetes. (R)-6-Fluoro-4-ureidochroman-4-carboxylic acid and its racemic modification are by-products from the production of sorbinil from 6-fluoro-4-chromanone.
