Abstract
4-Oxo-4,5,6,7-tetrahydrobenzofurazan, which is easily synthesized from cyclohexanone, can be efficiently converted to 4-(2-carboxyethyl)- and 4-[3-(E)-hydroxyimino)-3-nitropropyl]furazan-3-carboxylic acids by the oxidation with nitric acid. Subsequent alkaline oxidation provides a route to furazan-3,4-dicarboxylic acid.
