New derivatives with hydroxyl, amino, and keto groups; halides; and N atoms were synthesized based on available guaiane-type sesquiterpene lactones arglabin, artefin, ludartin, and estafiatin isolated from yarrow and wormwood. The structures of the molecules were established using IR, UV, PMR, and 13C NMR spectral data. The molecular structures of 2, 6, 12, and 14 were proved by x-ray crystal structure analyses.
根据从西洋蓍草和艾草中分离出来的现有愈创木型倍半萜内酯 arglabin、artefin、ludartin 和 estafiatin,合成了带有羟基、氨基和酮基以及卤化物和 N 原子的新衍生物。利用红外光谱、紫外光谱、PMR 光谱和 13C NMR 光谱数据确定了这些分子的结构。通过 X 射线晶体结构分析,证明了 2、6、12 和 14 的分子结构。
