In an article, author is Joyce, Eamonn, once mentioned the application of 40138-16-7, Recommanded Product: (2-Formylphenyl)boronic acid, Name is (2-Formylphenyl)boronic acid, molecular formula is C7H7BO3, molecular weight is 149.9397, MDL number is MFCD00151822, category is naphthyridines. Now introduce a scientific discovery about this category.
Acetic Anhydride Generated Imidazolium Ylide in Ring Closures onto Carboxylic Acids; Part of the Synthesis of New Potential Bioreductive Antitumor Agents
Acetic anhydride behaves as a traceless activating agent allowing thermal intramolecular condensation of 2-(benzimidazol-1-ylmethyl) benzoic and nicotinic acids. Autoxidation gives benzimidazo[1,2-b]isoquinoline-6,11-diones (intermediates characterized) and benzimidazo[2,1-g]-1,7-naphthyridine-5,12-diones in a facile, one-pot transformation. The 1,4-dimethoxy analogue of the former is converted into benzimidazo[1,2-b]isoquinoline-1,4,6,11-tetrone using cerium ammonium nitrate (CAN). The 1,7-naphthyridine-5,12-dione system readily ring-opens, and an X-ray crystal structure of the methanol adduct was obtained.
