    at room temperature the epoxide is completely solvolyzed to give the corresponding diol (hydrolysis) or vicinal hydroxyl-methoxy (methanolysis) derivative. All the compounds involved in the above reactions were characterized by IR, Raman, H NMR and UV–vis spectroscopies, and by mass spectrometry. Density functional theory (DFT) computations were used to optimize the structure conformations. The optimized
    摘要 药用植物 Sencecionutans 的主要代谢物 4HMBA 的环氧化作用会产生一种不稳定的环氧化物,最终形成四种衍生物的混合物,其中三种以前报道为天然产物环氧化物产物很容易受到羟基对环氧基碳的分子内攻击,以产生苯并呋喃色烷生物。当在室温下溶解在甲醇-混合物中时,环氧化物完全溶解,得到相应的二醇(解)或邻位羟基-甲氧基(甲醇分解)衍生物。参与上述反应的所有化合物均通过红外、拉曼、核磁共振和紫外-可见光谱以及质谱进行表征。密度泛函理论(DFT)计算用于优化结构构象。优化后的结构进一步进行了自然键轨道 (NBO) 和静电势分析。标题化合物(分别简称为3和4)的晶体结构通过X射线衍射法测定。化合物 3 在三斜 P-1 空间群中结晶,a = 6.4289 (6) A, b = 8.7120 (6) A, c = 10.952 (1) A, α = 92.280 (7)°, β
