INSECT SEX PHEROMONE SYNTHESIS OF Z-9-TETRADECENYL ACETATE
【摘要】 <正> 顺-9-十四碳烯-1-醇乙酸酯(1)是鳞翅目许多昆虫的性信息素或其组分之一。已报道的化合物1的合成方法是采取C10+C4或C9+C5偶联原则。本文报道另一条合成路线(图1),采取C8+C6原则,以1,8-辛二醇(2)为原料,经过ω-氯代辛醇(3)得2-(8′-氯辛烷-1-氧基)四氢吡喃(4)[2d],卤代物4与己炔-1(5)的锂盐缩合得炔化物6,然
【Abstract】 The title compound (1), the major compound of insect sex pheromone of summer tortrix moth (Adoxophes orana F. von R.)was synthesized in 5 steps with a 40% overall yield according to the C8+ C6 coupling principle, using 1, 8-octandiol as starting material. Namely, coupling of lithium salt of hexyne-1 with 2- (8’-chlorooctyloxy-) tetrahydropyrane gave 2-(9’-tetradecyloxy-)tetrahydropyrane, which was partially hydrogenated in the presence of Lindlar catalyst to form compound 7. Simultaneous deprotection and acetylation of 7 with acetyl chloride and acetic acid afforded the title compound 1. The isomeric purity of compound 1 was about 98% as shown by gas chromatography. The E isomer 9 was also synthesized from 6 by means of sodium-liquid ammonia reduction followed by acetylation.
