Methods for the preparation of alkenes including insect pheromones are described. The methods include homologation reactions employing reagents such as 1,3-diesters, epoxides, cyanoacetates, and cyanide salts for elongation of starting materials and intermediates by one or two carbon atoms. The alkenes include insect pheromones useful in a number of agricultural applications.
描述了制备烯烃(包括昆虫信息素)的方法。这些方法包括使用1,3-二酯、
环氧化物、
氰乙酸盐和
氰化物等试剂进行同系反应,通过增加一到两个碳原子来延长起始物质和中间体。这些烯烃包括在许多农业应用中有用的昆虫信息素。
