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).
本研究通过使用
铅(IV)
醋酸盐(LTA)、
铅(IV)
丙酸盐(LTP)、
汞(II)醋酸盐(MA)和
碘代
苯乙酸酯(IB
DA)对
α-蒎烯进行酰氧化反应,在中性和酸性介质中研究了
鼠尾草酸鹅绒藤酯(Ia)和
丙酸鹅绒藤酯(Ib)的合成。中性介质更有利于形成Ia和Ib,因为酸性介质有助于打开
α-蒎烯的
环丁烷环。这些方法可用于大规模制备对蟑螂种类(德国小蠊,东方小蠊和美洲大蠊)具有吸引作用的昆虫引诱剂。
