Some amphibians use chemical signals in addition to optical and acoustical signals to transmit information. Males of mantellid frogs from Madagascar and hyperoliid frogs from Africa emit complex, species- and sex-specific bouquets of volatiles from their femoral or gular glands. We report here on the identification, synthesis, and determination of the absolute configuration of a macrocyclic lactone
除了光学和声学信号外,一些两栖动物还使用化学信号来传输信息。马达加斯加的mantellid青蛙和非洲的hyperoliid青蛙的雄性从它们的股腺或喉腺中释放出复杂的、物种和性别特异性的挥发物束。我们在此报告了大环内酯绝对构型的鉴定、合成和测定,这些内酯存在于两个家族的几个物种中,(S)-3,7,11-dodec-6,10-dien-12-olide (S) -14,青蛙内酯)。大环内酯类是青蛙挥发物的优选化合物类别。然而,青蛙内酯是第一个明显来源于萜烯途径的大环内酯,与通常通过脂肪酸生物合成途径形成的已知青蛙大环内酯不同。
