Effect of the benzylic structure of lignan on antioxidant activity.

Abstract

The effect of the benzylic structure of lignan on antioxidant activity was evaluated. Secoisolariciresinol (1) and 3,4-bis(4-hydroxy-3-methoxybenzyl)tetrahydrofuran (2), which have two secondary benzylic positions without oxygen, showed the highest antioxidant activity. Optically active verrucosin (4) was synthesized for the first time in this experiment.
