Benzofurans compound 2-(3',4'-dihydroxyphenyl)-3-methoxy carbonyl-5-methoxy carbonyl vinyl-7-hydroxy-2,3-dihydrobenzofuran (1)and benzodioxanes compound 2-(3',4'-dihydroxyphenyl)-3-me-thoxy carbonyl-6-methoxy carbonyl vinyl-2,3-dihydro-1,4-benzodioxane (2)were synthesized from caffeic acid through esterification and biomimetic oxidative coupling reactions.Moreover,a series of benzofuran-neolignan compounds 3~7 and benzodioxaneneolignan compounds 8~10 were synthesized from compounds 1 and 2 respectively through acetylation,DDQ oxydehydrogenation,Pd/C catalytic hydrogenation,lithium aluminium hydride reduction and deacetylation in alkaline condition.All of these synthesized compounds were confirmed with MS,IR,1 H NMR and 13 C NMR spectra.Among them,5~7,9 and 10 are new com-pounds.8 is the natural product isoamericanol A.The biological activities of benzofuranneolignan com-pounds 1 ,3~5 against five human cancer cell lines were evaluated in the standard MTT method,and the results have shown that compounds1,3,4 and 5 exhibit good inhibitory effect on leukemia cells (HL-60), lung carcinoma cell (A-549),breast cancer cell (MCF-7),colon cancer cell (SW-480),and hepatoma car-cinoma cell (SMMC-7 7 2 1 ).
