Neolignans fromAniba ferrea

Abstract The presence of benzyl benzoates as well as of bicyclo [3.2.1] octanoid and hydrobenzofuranoid neolignans in Aniba ferrea was confirmed by the isolation of additional representatives of this class of natural products. The hydrobenzofuranoids included three novel ferrearins which, considered together with four known ferrearins, led to the stereochemical clarification of the group.
