The present invention relates to a process for producing an E,Z-9-alkenyl-1-aldehyde component which comprises: (a) disproportionating cyclooctene and an .alpha.-olefin in the presence of a suitable disproportionation catalyst under disproportionation conditions suitable to form a 1,9-alkadiene; (b) reacting the 1,9-alkadiene obtained in step (a) with a suitable metallating agent under conditions suitable to form a 1-metallo-9-alkene; (c) contacting the 1-metallo-9-alkene obtained in step (b) with oxygen under conditions suitable to form a 1-oxymetallo-9-alkene; (d) hydrolyzing the 1-oxymetallo-9-alkene suit a suitable hydrolyzing agent, under suitable hydrolyzing conditions to form E,Z-9-alkenyl-1-alcohol. (e) oxidizing said E,Z-9-alkenyl-1-alcohol with a suitable oxidizing agent under oxidizing conditions suitable to form E,Z-9-alkenyl-1-aldehyde. Another aspect of the invention pertains to a composition comprising Z-11-hexadecen-1-al, Z-9-tetradecen-1-al and E-9-tetradecen-1-al admixed in sufficient quantities to possess pheromone-like activity for Heliothis zea and Heliothis virescens.
本发明涉及一种生产E,Z-9-烯基-1-醛组分的方法,该方法包括:(a)在适当的不均化催化剂存在下,在适宜的不均化条件下,使环辛烯和α-烯烃不均化反应生成1,9-烷二烯;(b)在适宜的金属化试剂存在下,以适宜的条件使步骤(a)中获得的1,9-烷二烯与金属化试剂反应形成1-金属基-9-烯烃;(c)在适宜的条件下,使步骤(b)中获得的1-金属基-9-烯烃与氧接触,形成1-氧基金属基-9-烯烃;(d)在适宜的水解试剂存在下,在适宜的水解条件下,使1-氧基金属基-9-烯烃水解生成E,Z-9-烯基-1-醇;(e)在适宜的氧化条件下,使用适宜的氧化试剂将所述E,Z-9-烯基-1-醇氧化成E,Z-9-烯基-1-醛。本发明的另一个方面涉及一种组合物,该组合物包括Z-11-十六烯-1-醛、Z-9-十四烯-1-醛和E-9-十四烯-1-醛,混合在足够的量中具有对玉米螟和绿色玉米螟具有类似信息素的活性。
