  The present invention relates to metathesis syntheses for insect sex-attractant pheromones or their components, such as E-5-decenyl acetate, the major component of the Peach Twig Borer pheromone; (5R, 6S)-6-acetoxy-5-hexadecanolide, the mosquito oviposition attractant pheromone; E9, Z11-hexadecadienal, the pecan nut casebearer moth pheromone; 9-tetradecenyl formate, an analog of the Diamondback Moth (DBM) pheromone; 11-tetradecenyl acetate, the Omnivorous Leafroller (OLR) pheromone; E-4-tridecenyl acetate, the major component of the Tomato Pinworm (TPW) pheromone; E,E-8,10-dodecadienol, the Codling Moth (CM) pheromone. The syntheses preferably employ a Class I-IV metathesis catalyst, entail few reaction steps, use generally commercially available starting materials, and have relatively short process times. These syntheses produce good yields without the need for expensive or sophisticated equipment. The invention also provides an inexpensive route for producing omega-haloalkenols by cross-metathesizing alpha-omega-diacetoxy alkenes and alpha-omega-dihalides to yield omega-haloalkenols, which are easily converted into omega-haloalkanols under traditional hydrogenation methods.

  本发明涉及对昆虫性诱素或其组分进行交换合成，如E-5-癸烯醇醋酸酯，桃枝蠕蛾性信息素的主要成分；（5R, 6S）-6-乙酰氧基-5-十六醇内酯，蚊子产卵引诱素；E9, Z11-癸二烯醛，山核桃果蛾性信息素；9-十四烯酸甲酯，菜青虫性信息素的类似物；11-十四烯醇醋酸酯，杂食卷叶蛾性信息素；E-4-十三烯醇醋酸酯，番茄针孔螟性信息素的主要成分；E,E-8,10-十二二烯醇，苹果蛾性信息素。这些合成通常采用I-IV类交换催化剂，步骤较少，使用通常易得的起始物质，并具有相对较短的工艺时间。这些合成产量良好，无需昂贵或复杂的设备。该发明还提供了通过交叉交换α-Ω-二乙酰基烯烃和α-Ω-二卤代烃来产生Ω-卤代烯醇的廉价途径，后者可以在传统的氢化方法下轻松转化为Ω-卤代烷醇。

  Reaction mixtures and methods using catalysts and reaction conditions to produce significantly improved yields (and thereby higher purity) of olefin metathesis products, with greatly reduced amounts of impurities. These techniques include in one instance reduction in temperature of reaction, and in another, the use of chemical compounds that act as reaction inhibitors of unwanted reactions to minimize or prevent formation of unwanted impurities.

  反应混合物和方法使用催化剂和反应条件，以产生显著提高烯烃交换产物的收率（从而提高纯度），并大大减少杂质的量。这些技术包括在一种情况下降低反应温度，在另一种情况下使用化学化合物作为不需要反应的反应抑制剂，以最小化或防止不需要的杂质的形成。

  Methods for preparation of olefins, including 8- and 11-unsaturated monoenes and polyenes, via transition metathesis-based synthetic routes are described. Metathesis reactions in the methods are catalyzed by transition metal catalysts including tungsten-, molybdenum-, and ruthenium-based catalysts. The olefins include insect pheromones useful in a number of agricultural applications.
