The tetracyclic diterpenoids are quite widespread in nature. Their biogenesis takes place through the cyclization of suitably oriented pimaradienes'. As an aid to the structural determination of new compounds of this type, we have analysed the 13C NMR spectra of a series of compounds with the ent-be

The first three natural ent-halimanolides known until now have been synthesized from ent-halimic acid. Their structure have been confirmed as well as their absolute configurations established. Bestmann methodology has been used for the synthesis of butenolides and for the g-hydroxybutenolides synthe
