The 6-hydroxychromans (4) and (6), and 5-hydroxy-2,3-dihydrobenzo[b]furans (5) and (7) bearing a 4-hydroxypyran-2-one moiety were synthesized. All the compounds exhibited potent activity against lipid peroxidation. The chroman (4) possessed inhibitory activity against HMG-CoA reductase in addition to the antioxidant character.
