结果表明，木质素模型化合物4,6-二（叔丁基）愈创木酚(I)在漆酶作用下裂解成芳香环产物2,4-二（叔丁基）-4-（甲氧基羰基甲基）-2-丁-4-olide （II）。通过与18o2h218o的同位素实验，探讨了其形成机理。
It was found that 2,4-di(tert-butyl)-4-(methoxycarbonylmethyl)-2-buten-4-olide (II) was formed as an aromatic ring cleavage product of a phenolic lignin model compound, 4,6-di(tert-butyl)guaiacol (I), by laccase ofCoriolus versicolor. Based on isotopic experiments with18O2H218O, the mechanism of formation ofIIfromIis discussed.
