The mononuclear complex, FeIII(O-bs)(salen) (salenH2 = 1,6-bis(2-hydroxyphenyl)-2,5-diaza-hexa-1,5-diene; O-bsH = O-benzoylsalicylic acid) was synthesized as synthetic enzyme-depside complex, and characterized by spectroscopic methods and X-ray crystal analysis. The dioxygenation of flavonol (flaH) and 3-hydroxy-4-quinolone (quinH2) derivatives in the presence of catalytic amounts of FeIII(O-bs)(salen)
单核络合物Fe III(O -bs)(salen)(salenH 2 = 1,6-双(2-羟基苯基)-2,5-二氮杂-六-1,5-二烯; O -bsH = O-苯甲酰水杨酸 酸)合成为合成的酶-深度复合物,并通过光谱法和X射线晶体分析进行了表征。在催化量的Fe III(O -bs)(salen)存在下,黄酮醇(flaH)和3-羟基-4-喹诺酮(quinH 2)衍生物的双氧化作用导致杂环的氧化裂解,得到相应的Ø-苯甲酰基水杨酸和邻氨基苯甲酸衍生物,同时释放一氧化碳。这些反应可以被认为是仿生功能模型,与含铁的黄酮醇和不依赖辅因子的3-羟基-4(1 H)-喹诺酮2,4-二加氧酶有关。
