Recent reports have suggested the use of the relative abundances of long chain (n-C37) alken-2-ones (1, 2, and 3) in Quaternary marine sediments as a palaeoclimate indicator1. Here we report the synthesis of these ketones with all-E and all-Z stereochemistry. Use of the synthesised compounds has shown that the natural counterparts in the alga and in marine sediments have the unusual and unexpected
最近的报告建议在第四纪海洋沉积物中使用长链(n -C37)烯烃-2-酮(1、2和3)的相对丰度作为古气候指标1。在这里,我们报告了具有全E和全Z立体化学的这些酮的合成。合成化合物的使用表明,藻类和海洋沉积物中的天然对应物具有不同寻常且出乎意料的E构型。
