The trunk wood of an Amazonian Aniba (Lauraceae) species contains, besides dillapiol and the benzodioxane-type neolignan eusiderin, four bicyclo(3.2.l)octanoid neolignans. These comprise representatives of the canellin-type: the known methoxycanellin-A and the novel compounds characterized as (lR, 3S, 4S, SS, 6S, 7R)-1-allyl-4-hydroxy-3, 5-dimethoxy-7-methyl-6-(3'-methoxy-4', S-methylenedioxyphenyl)-8-oxobicyclo(3.2.l)octane; (lR, 3S, 4S, SS, 6S, 7R)-1-allyl-4-hydroxy-3, 5-dimethoxy-7-methyl&(3', 4', 5'-trimethoxyphenyl)-8-oxobicyclo(3.2.l)octane and (lR, 4R, 5R, 6S, 7R, 8S)-l-allyl-4, 8-dihydroxy-5-methoxy-7 methyl-6-(3'-methoxy-4, 5'-methylenedioxyphenyl)-3-oxobicyclo(3.2.l)octane.
