The snow flea Ceratophysella sigillata, a winter‐active species of springtail, produces unique polychlorinated octahydroisocoumarins to repel predators. The structure of the major compound, sigillin A, was elucidated through isolation, spectroscopic analysis, and X‐ray crystallography. Sigillin A showed high repellent activity in a bioassay with predatory ants. A promising approach for the total synthesis
跳蚤的雪地跳藻(Ceratophysella sigillata)是一种具有冬季活动性的跳尾物种,可产生独特的多氯八氢异香豆素,以击退食肉动物。通过分离,光谱分析和X射线晶体学阐明了主要化合物sigillin A的结构。Sigillin A在具有掠食性蚂蚁的生物测定中显示出很高的驱避活性。还开发了一种有希望的方法来完全合成这类新的天然化合物的成员。
