NEPETALACTON Chemical Properties,Usage,Production

Uses

cis-trans-Nepetalactone, is an organic compound, isolated from the plant catnip,which acts as a cat attractant. Nepetalactone can also be effective on some insects. It repels cockroaches and mosquitos.

Definition

ChEBI: Cis-trans-nepetalactone is a cyclopentapyran that is (4aS,7aR)-1,4a,5,6,7,7a-hexahydrocyclopenta[c]pyran substituted at position 1 by an oxo group and at positions 4 and 7 by methyl groups, respectively (the 4aS,7S,7aR-diastereomer). An iridoid monoterpenoid isolated from several Nepeta plant species. It is an aphid sex pheromone and cat attractant, and exhibits antibacterial, antifungal, and analgesic properties. It has a role as a pheromone, a plant metabolite, an insect attractant, an analgesic, an insect repellent, an antibacterial agent and an antifungal agent. It is an iridoid monoterpenoid and a cyclopentapyran.

Production Methods

Nepetalacton can be produced 1) by isolation from American catnip oil (about 45% lactone). 2) synthetic, from Ethyl-3-methyl-2-oxocyclopentane carboxylate with Bromo butyne.
