Abstract

A key intermediate responsible for anthrahydmquinone-(AHQ-) catalyzed delignification of wood under alkaline conditions is an adduct between AHQ and a quinone methide (QM) of a phenylpropanoid lignin subunit represented by models such as 1-(3-methoxy-4- hydroxyphenyl)-2-(2-methoxyphenoxy) propane-1, 3-diol. Unlike adduct formation via QMs, which give only threo products with AHQ or anthranol (9-hydroxyanthracene), both ...
