摘要：

On the basis of spectroscopic evidence, eupodienone-8 and -9, isolated from the flowers of Eupomatia laurina R. Br., are assigned the structures (5R, 7R, 8R)-3′, 4-dimethoxy-7, 8-dimethyl-2, 3- methylenedioxy-6, 7, 8, 9-tetrahydrospiro[5H-benzocycloheptene-5, 1′-cyclohexa-2′, 5′-dien]- 4′-one (9) and (5S, 7R, 8R)-3′, 4-dimethoxy-7, 8-dimethyl-2, 3-methyIenedioxy-6, 7, 8, 9-tetrahydro- spiro[5H-benzocycloheptene-5, 1′-cyclohex-2′, 5′-dien]-4′-one (10) respectively. The products of dienone-phenol rearrangement of these substances are characterized; eupodienone-8 unexpectedly rearranges with aryl group migration. Eupomatenoid-1 and -7, eupodienone-6 and (-)-dihydroguaiaretic acid were also isolated. © 1990 ASEG.
