Cembranoids, Pseudopteranoids, and Cubitanoids of Natural Occurrence
1992The structures of (+)-cembrene (1), a macrocyclic diterpene hydrocarbon isolated from pine oleoresins (1, 2), and of the two epimeric cembratrienediols 35 and 36, which were obtained from tobacco (3), were reported in 1962. Since these pioneering studies, the structures of some 300 naturally occurring cembranoids have been resolved.

Mode of cembranoid action on embryonic muscle acetylcholine receptor
Journal of Neuroscience Research, 2007AbstractThe mechanism of eupalmerin acetate (EUAC) actions on the embryonic muscle nicotinic acetylcholine receptor (nAChR) in BC3H‐1 cells was studied by using whole‐cell and single‐channel patch‐clamp current measurements. With whole‐cell currents, EUAC did not act as an agonist on this receptor. Coapplication of 30 μM EUAC with 50 μM, 100 μM, or 500

Strategies for the Total Synthesis of C2−C11 Cyclized Cembranoids
Chemical Reviews, 2008The C2-C11 cyclized cembranoids, which include the eunicellins (also known as the cladiellins), briarellins, asbestinins, and sarcodictyins, are secondary metabolites isolated from gorgonian octocorals and soft corals. An unusual oxatricyclic ring system containing a hydroisobenzofuran and an oxonene unit with stereogenic centers residing at C1-3, 9 ...

Total Synthesis of Sarcophytol A, an Anticarcinogenic Marine Cembranoid
The Journal of Organic Chemistry, 1994A highly stereo- and enantioselective total synthesis of sarcophytol A (1), a marine cembranoid promising as a cancer chemopreventive agent, is described. The nitrile 10 obtained Z-selectively (Z:E=>35:1) by the Horner-Emmons reaction of (E,E)-farnesal (5) with the phosphononitrile 9 in 91% yield was converted to the conjugated 2(Z),4(E)-dienal 3 in ...

Recent Advances in Synthesis of the Polycyclic Norcembranoid and Cembranoid Diterpenoids
Chemistry – A European JournalAbstractThe C19 norcembranoid and C20 cembranoid diterpenoids represent an intriguing class of natural products found in both marine and terrestrial environments. These complexes, with a highly oxygenated state and compact polycyclic structures, have captured the synthetic interests due to their unique bioactivities.
