β¦ Synopsis
The reactions of quinone methide intermediates during the initial biosynthesis and also the subsequent aging of lignin are reviewed. The reactions during aging should lead to enhanced lignin-carbohydrate bonding and may explain the structural and analytical differences found between DHP and isolated milled wood lignins.

The intermediacy of the quinone methide 1 in the photochemical transformations of spirodienone 2 was deduced on the basis of formation of the ether-incorporated product 3\* (2,3) This postulate was strengthened as a result of experiments with spirodienone 1 labeled with deuterium on the cyclopropane
