potassium disilazide as the base gives (Z)-3-alkenoate predominantly. A trail-following pheromone for subterranean termites is synthesized stereoselectively with this method. Deconjugative protonation of trienolates from (E,E)-2,4-tetradecadienoates gives (E,Z)-3,5-tetradecanoates which is hydrolyzed to give Megatomoic acid, a sex pheromone for a black carpet beetle Attagenus megatoma.
以二硅叠氮化钾为碱,从(E)-2-链烯酸酯二烯酸酯的共轭解质子化反应主要产生(Z)-3-链烯酸酯。用这种方法立体选择性地合成了用于地下白蚁的跟踪信息素。从(E,E)-2,4-十四碳二烯酸酯中分离出三烯酸酯的共轭质子化得到(E,Z)-3,5-十四碳酸酯,其水解后得到Megatomoic酸,一种黑色地毯甲虫Attagenus megatoma的性信息素。
