Aromatic ring cleavage of 4,6-di(tert-butyl)guaiacol, a phenolic lignin model compound, by laccase of Coriolus versicolor

FEBS Lett. 1988 Aug 29;236(2):309-11. doi: 10.1016/0014-5793(88)80043-7.

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.
