Model compounds for the dibenzodioxocine structure, a new structural unit recently discovered in wood lignins, have been synthesised by two different methods. In one route, the 8-membered ring is formed by ring closure of an arylglycerol β-aryl ether with

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.
