Several 5-deaza-10-oxaflavin (2H-chromeno[2, 3-d]pyrimidine-2, 4(3H)dione) derivatives (1) were prepared in satisfactory yields through new, practical routes. These 5-deaza-10-oxaflavins showed a strong redox property in the oxidation of some alcohols to the corresponding carbonyl compounds under slightly acidic conditions, while they were reduced to the stable 1, 5-dihydro derivatives. Participation of a direct hydride transfer from the alcohol was demonstrated by an experiment using deuterium-labeled alcohol.
几种5-deaza-10-氧氟黄素(2H-铬酮[2, 3-d]嘧啶-2, 4(3H)二酮)衍生物(1)通过新的、实用的路线,以令人满意的产率制备而成。这些5-deaza-10-氧氟黄素在稍微酸性条件下显示出强的氧化还原性能,能够将一些醇氧化为相应的羰基化合物,同时它们被还原为稳定的1, 5-二氢衍生物。使用氘标记的醇进行的实验证明了醇的直接氢转移参与了反应。
