The fungus among us: The cyclization mechanism of the bioactive, unique, tetracyclic diterpene harzianone, produced by the biocontrol fungus Trichoderma, was studied by feeding experiments using synthetic mevalonolactone isotopologues. Results were captured with a closed-loop stripping apparatus (CLSA) and directly analyzed by ¹³C NMR spectroscopic methods.
