Abstract

A large panel of novel catecholic antioxidants and their fatty acid or methyl carbonate esters has been synthesized in satisfactory to good yields through a 2-iodoxybenzoic acid (IBX)- mediated aromatic hydroxylation as the key step. The new catechols are structural analogues of naturally occurring hydroxytyrosol (3, 4-DHE). To evaluate structure/activity relationships, the antioxidant properties of all catecholic compounds were evaluated in ...
