4-decadienoate (1), an important pheromone component of Pityogenes chalcographus, and its three geometrical isomers (2–4) have been synthesized and obtained in 99 % isomeric purity. Urea inclusion complexes were used in the final purification procedures. Spectroscopic data (MS, 1H and 13C NMR) of all four isomers are discussed. A photoisomerization study of the decadienoates is presented.
(2 E,4 Z)-2,4-癸二烯酸甲酯(1 E),Pityogenes chalcographus的重要信息素成分,及其三种几何异构体(2-4)均已合成,纯度为99%。在最终的纯化程序中使用了尿素包合物。讨论了所有四个异构体的光谱数据(MS,1 H和13 C NMR)。提出了癸二烯酸酯的光异构化研究。
