摘要：

Oxidation of o,o'-dihydroxybiphenyl compounds together with coniferyl alcohol yields substituted 6,7-dihydro-dibenzo-(e,g)(1,4)-dioxocins, that represent a novel type of linkage in softwood lignins. The mechanism of formation of the 8-membered ring involves intramolecular nucleophilic addition to an intermediate quinone methide structure.
