Abstract The structure of the diterpene nimbinone 1b has been confirmed by syntheses via a cascade cyclisation and also from podocarpicacid by two separate series of transformations. Synthesis of structure 3b from dehydroabietic acid shows that this does not exhibit the properties described for nimbosodione.
