Improved syntheses are described for nagilactone F and the antibiotic LL-Z1271 alpha, two of the most potent bioactive members of the podolactone family. The allelopathic potential of some members of this podolactone series has been evaluated, with the result that the metabolite LL-Z1271 alpha is one of the most active compounds.

Total Synthesis of Oidiodendrolides and Related Norditerpene Dilactones from a Common Precursor: Metabolites CJ-14,445, LL-Z1271γ, Oidiolactones A, B, C, and D, and Nagilactone F
An efficient, high-yielding strategy has been developed for the asymmetric total synthesis of seven norditerpenoid dilactones known for their diverse biological properties. The three key steps employed to obtain a tricyclic lactone intermediate involved a Morita−Baylis−Hillman reaction, the stereocontrolled construction of a γ-lactone through bromolactonization, and an efficient catalytic Reformatsky-type
