endo-alkyl- and hydroxyalkyl-substituted bicyclo[n.1.0]alkan-1-ols with (diacetoxy-λ3-iodanyl)benzene gave the corresponding methyl alkenoates exclusively with E or Z configuration of the double bond. This reaction was used as the key stage in the syntheses of stereoisomerically pure components of pest insect pheromones: (E)-dodec-9-en-1-yl acetate (European pine shoot moth Rhyacionia buoliana), (Z)-tetradec-11-en-1-yl
的氧化裂解外-和内-烷基-和羟烷基取代的双环[ Ñ .1.0]的烷-1-醇与(乙酰氧基λ 3 -iodanyl)苯,得到相应的甲基烯酸酯只与Ë或Ž双键的构型。该反应被用作害虫昆虫信息素的立体异构纯组分合成的关键阶段:(E)-dodec-9-en-1-yl乙酸酯(欧洲松枝蛾Rhyacionia buoliana),(Z)-tetradec -11 -en-1-yl醋酸盐(欧洲橡木卷叶草Tortrix viridana)和(3 E,8 Z,11 Z)-十四烷基-3,8,11-三烯-1-基乙酸酯(番茄切叶机Tuta absoluta)。
