Description

General description

Myrcene is a monoterpene. Males of Ips spp. produced the pheromones ipsdienol (2-methyl-6-methylene-2,7-octadien-4-ol) and/or ipsenol (2-methyl-6-methylene-7-octen-4-ol) on exposure to the vapours of myrcene. Myrcene serves as a precursor for terpene alcohols. Myrcene is a constituent of the beetle′s host, ponderosapine. Hydrogenation of myrcene catalyzed by Ru, Cr, Ir and Rh complexes yields a complex mixture of mono-, di- and trihydrogenated products.

Application

Myrcene is the suitable synthetic standard used in the identification of E-myrcenol (2-methyl-6-methylene-E-2,7-octadien-1-01) as a major hindgut constituent in Eurasian bark beetle Ips duplicatus by GC-MS.
