dimethylated fatty acid 9,13-dimethyltetradecanoic acid was identified for the first time in nature in the Caribbean sponge Calyx podatypa where it occurs together with the rare 10, 13-dimethyltetradecanoic acid. The characterization of the novel compound was accomplished using GC-MS, pyrrolidide derivatization, and a five-step total synthesis starting with 8-bromooctanoic acid. The first racemic total synthesis
自然界中首次在加勒比海海绵花萼中发现了二甲基化脂肪酸9,13-二甲基十四烷酸,它与稀有的10,13-二甲基十四烷酸一起出现。使用GC-MS,吡咯烷化物衍生化以及从8-溴辛酸开始的五步全合成完成了新化合物的表征。还描述了稀有的10,13-二甲基十四烷酸的首次外消旋全合成。
