title: Structure confirmation of a bioactive lactone isolated from Otoba parvifolia through the synthesis of a model compound.
abstract: Synthesis of a model compound 4 structurally related to a bioactive lactone 3 isolated from Otoba parvifolia has been accomplished. The good match between the NMR data of both compounds suggests they have identical bicyclic [3.3.1] carbon skeletons.
