triple bond functionalities were used to introduce the diagnostic (C13 or C14) and tagging (C8 and C9) labels, respectively, in the palmitic acid skeleton. Using these probes, the cryptoregiochemistry of the Δ13 desaturation involved in the biosynthesis of Thaumetopoea pityocampa sex pheromone was studied by means of kinetic isotope effect determinations. Transformation of both (Z)-11-hexadecenoic and
两个六氘棕榈酸在诊断标签的位置不同的合成,和它们的用途破译一个Δ的cryptoregiochemistry 13去饱和中描述。使用二噻吩和三键功能分别在棕榈酸骨架中引入诊断(C13或C14)标签和标签(C8和C9)标签。使用这些探针中,Δ的cryptoregiochemistry 13参与的生物合成去饱和Thaumetopoea pityocampa性信息素是由动力学同位素效应测定的方法研究。(Z)-11-十六碳烯酸和11-十六碳烯酸均转化为(Z,Z)-11,13-十六碳二烯酸和(Z)-13-十六碳烯-11炔酸分别通过以下方式引发:在C13位置提取氢原子,然后快速消除C14氢以生成双键。
