Abstract
It was found that 2,4-di(tert-butyl)-4-(methoxycarbonylmethyl)-2-buten-4-ol ide (II) was formed as an aromatic ring cleavage product of a phenolic lignin model compound, 4,6-di(tert-butyl)guaiacol (I), by laccase of Coriolus versicolor. Based on isotopic experiments with 18O2 and H2 18O, the mechanism of formation of II from I is discussed.
摘要
发现2,4-二（叔丁基）-4-（甲氧羰基甲基）-2-丁烯-4-内酯（II）是云芝漆酶作用于酚类木质素模型化合物4,6-二（叔丁基）愈创木酚（I）时形成的芳环裂解产物。基于用18O2和H2 18O进行的同位素实验，讨论了由I形成II的机理。
