摘要：

On the basis of spectroscopic evidence, the eupomatilones (from eupomatilone-1 to -7) isolated from Eupomatia bennettii F. Muell. were shown to be degraded lignans. Eupomatilone-1 was assigned the structure (1), cis-4-methyl-3-methylene-5-(3'',4'',5'',6'-tetramethoxy-4',5'-methylenedioxybiphenyl-2'-yl) dihydrofuran-2(3H)-one. The other six eupomatilones differ from eupomatilone-1 either in the degree of oxygenation of the biphenyl system or in the substitution of the furanone ring. Atropisomerism was observed with the compounds.
