Antioxidants are important in preventing oxidative stress by scavenging oxygen free radicals. In this study, a series of 2,2-dimethyl-2,3-dihydrobenzofuran-5-ols with amino, methoxy, chloro and nitro groups at the ortho position relative tothe phenolic OH group were newly synthesized, and their galvinoxyl and hydroxyl radical scavenging activities were measured. Substituted 2,3-dihydrobenzofuran-5-ols showed higher activity than the corresponding 6-chromanols, especially 6-amino-2,2-dimethyl-2,3-dihydrobenzofuran-5-ol, which possessed the highest activity among the tested compounds. The results demonstrated that the planarity and electron-donating capacity of these molecules enhanced their radical scavenging activities, as is known for 6-chromanols.
