ketoesters followed by enzymatic saponification. The acids 1-3 were evaluated in vivo as inhibitors of the beta-oxidation step of the biosynthesis of (Z,E)-9,11-tetradecadienyl acetate, the major component of the sex pheromone of the Egyptian armyworm Spodoptera littoralis. Only, the 2,2- and 3,3-derivatives, i.e. those containing the two fluorine atoms at the positions involved in the chain-shortened
已经合成并充分表征了2,2-,3,3-和4,4-二氟棕榈酸(1-3)。通过氟化相应的二硫缩醛保护的酮酸酯,然后进行酶促皂化,可以制备酸2和3。在体内评估了酸1-3作为生物合成(Z,E)-9,11-十四碳二烯基乙酸酯的β-氧化步骤的抑制剂的作用,该乙酸酯是埃及夜蛾夜蛾斜纹夜蛾性信息素的主要成分。仅发现2,2-和3,3-衍生物,即那些在链缩短步骤中所涉及的位置含有两个氟原子的衍生物是活泼的,其活度类似于或低于相应的单氟酸。
