Aliphatic macrolides are used by various organisms as semiochemicals or pheromones, e. g. by the endemic Madagascan frog family Mantellinae. Volatile, methyl-branched aliphatic macrolides occur in various species, but their identification by MS is difficult, while isolation is not possible due to the low amounts produced. Therefore, we synthesized a library of methyl-branched 11-dodecanolides to identify
脂肪族大环内酯类被各种生物用作信息化学物质或信息素,例如地方性的马达加斯加青蛙家族Mantellinae。挥发性的,甲基支化的脂肪族大环内酯类化合物种类繁多,但通过MS鉴定它们很困难,而由于产量低,无法进行分离。因此,我们合成了一个甲基支链的11-十二烷内酯库,以鉴定由Gephyromantis moseri(一种只限于热带雨林且主要以陆地生境为特征的曼陀罗蛙)分泌的未知大环内酯类化合物。合成过程以金属有机环氧化物的开环和闭环复分解为关键步骤。因此,通过比较它们的质谱和气相色谱保留指数,可以确定所有的库成员2-,4-,6-,8-和10-甲基-11-十二烷醇化物是该分泌物的一部分。
