                                    Abstract(2E,4E,7R)‐farnesa‐2,4,10‐triene(Caparratriene) (1), a novel sesquiterpene hydrocarbon with significant growth inhibitory activity against CEM leukemia cells, was first synthesized from (R)‐(+)‐citronellal (2) by employing titanium‐induced intermolecular carbonyl‐coupling as the key step. The absolute configuration of (+)‐Caparratriene was determined to be 7R.
