Investigation of the Synthesis of Verbenyl Compounds, Effective Attractants of Cockroach Species, by Acyloxylation of α-Pinene

Abstract

The synthesis of verbenyl acetate (Ia) and propionate (Ib) was investigated by acyloxylation of α-pinene with lead(IV) acetate (LTA), lead(IV) propionate (LTP), mercury(II) acetate (MA) and iodosobenzene diacetate (IBDA) in neutral and acidic medium. The neutral medium is better for the formation of Ia and Ib, because the acidic medium helps the opening of cyclobutane ring of α-pinene. These methods can be used for large scale preparation of insect attractants to cockroach species (Blatella germanica, Blatella orientalis and Periplaneta americana).
