Diterpenes of Azadirachta indica. Syntheses to confirm structure

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