  通过向醛中添加改性的同烯酸钛，可轻松获得芳香活性不饱和γ-内酯

  摘要：

  均一Reformatsky反应（其中将酯的金属均烯酸酯添加到醛中）适用于从不饱和的可烯醇化的醛中生产γ-内酯。通过使用高纯钛酸钛，一步合成11种不同的γ-内酯，从容易获得的醛中获得中等至良好的收率。特别地，该方法允许快速制备一系列在双键的位置和构型上不同的C 12不饱和γ-内酯。这些参考化合物将用于鉴定黄油中以前未知的内酯。提供了合成内酯的色谱，光谱和感官描述。

  Provided is a water dispersion type sex pheromone sustained release preparation which makes it possible to suppress excess release at the initial stage of spraying and release a sex pheromone substance at a constant amount for a predetermined period, and which can be sprayed by using a common sprayer. Specifically provided is a water dispersion type sex pheromone sustained release preparation, comprising an insect sex pheromone substance which is enclosed in a ring of a cyclodextrin, an inclusion cyclodextrin which encloses the insect sex pheromone substance, a non-inclusion cyclodextrin which does not enclose the insect sex pheromone substance, a water-soluble polymer, and water. Furthermore, provided is a method for producing a water dispersion type sex pheromone sustained release preparation, comprising at least a step of mixing an aqueous suspension of an insect sex pheromone substance which is enclosed by a cyclodextrin, with a non-inclusion cyclodextrin which does not enclose the insect sex pheromone substance, and a water-soluble polymer.

  提供的是一种水分散型性信息素持续释放制剂，可以在喷洒的初始阶段抑制过度释放，并在预定期间以恒定的量释放性信息素物质，可以使用普通喷雾器喷洒。具体提供的是一种水分散型性信息素持续释放制剂，包括显微环糊精环封闭的昆虫性信息素物质、包裹昆虫性信息素物质的包含环糊精、不包裹昆虫性信息素物质的非包含环糊精、水溶性聚合物和水。此外，提供了一种制备水分散型性信息素持续释放制剂的方法，包括至少混合昆虫性信息素物质的水悬浮液，该水悬浮液由环糊精封闭，并与不包裹昆虫性信息素物质的非包含环糊精和水溶性聚合物混合的步骤。
