title: [Synthesis and biological activity of 2,3-benzopyrone analogs].
abstract: Several 2, 3-benzopyrone analogs were synthesized for evaluating their K(+)-channel and anticancer activities. The Friedel-Crafts reaction was taken place with some replacement phenyl acetic acid or its methyl ester and vanillin as reactants in the condition of Ac2O/ZnCl2. All products were confirmed by means of MS and 1H, 13CNMR spectra. Compounds 2 and 3 showed obvious activities on the K(+)-channel and anticancer screening, while the activity of compound 5 was weak. Compound 4 was not yet tested. The primary result indicate that the potential activity of such compounds deserves further study.
