| synthesis of the racemate of (z)-exo-alpha-bergamotenal, a pheromone component of the white-spotted spined bug, eysarcoris parvus uhler. | the racemate of (z)-exo-alpha-bergamotenal, a sex pheromone component of the white-spotted spined bug, was synthesized from racemic exo-alpha-bergamotene by a five-step sequence involving regioselective epoxidation and (z)-selective wittig olefination reactions. the 1h- and 13c-nmr spectra of the synthetic sample were identical with those of the natural material. | 2002 | 12162572 |
