Ausdem Gummiharz von Commiphoramukul Engl. (Burseraceae) (indisches “Guggul”‐Harz) wurden die monocyclischen Diterpene α‐Camphoren (2) und Cembren (4) isoliert. Für einen Diterpen‐Alkohol “Allylcembrol” wird die Struktur des 2‐Hydroxy‐4.8. 12‐trimethyl‐isopropyl‐cyclodecatriens‐(3.7.11) (6) vorgeschlagen. 6 wurde auch in den getrockneten oberirdischen Teilen von C. mukul nachgewiesen.

A direct approach of low-valent titanium-induced intramolecular keto ester cyclization was first applied to the total syntheses of macrocyclic diterpenoids, by which (±)-mukulol and (±)-cembrene were synthesized from geranylacetone by a short and efficient route.
