molecular structures of the title compounds were elucidated with the employment of physical measurements and spectroscopic techniques (FTIR, 1D and 2D NMR). The conformation of 7-decanoyloxy-3-(4′-methylphenyl)-4 H -1-benzopyran-4-one was determined by single crystal X-ray diffraction analysis of which the title compound crystallized into triclinic lattice with P -1 space group. Crystal structure of the
摘要 六种新的异黄酮基酯,7-decanoyloxy-3-(4'-locatedphenyl)-4 H -1-benzopyran-4-ones,衍生自 1,3-苯二醇(间苯二酚)和不同的对位取代苯乙酸。合成和表征。采用物理测量和光谱技术(FTIR、1D 和 2D NMR)阐明了标题化合物的分子结构。7-decanoyloxy-3-(4'-methylphenyl)-4 H -1-benzopyran-4-one的构象由单晶X射线衍射分析确定,其中标题化合物结晶为具有P -1 空间的三斜晶格团体。标题化合物的晶体结构还表明,中心部分的两个苯环是平面的,而发现杂环从平均平面略微起皱。
