摘要
开发了一种制备基于呋喃-2(3H)-酮和色烯-4(4H)-酮的杂化化合物(E)-3-{[2-氧代-5-芳基呋喃-3(2H)-亚基]甲基}-4H-1-苯并吡喃-4-酮的定向方法，其结构已通过元素分析、红外光谱、紫外光谱、核磁共振光谱和 X 射线单晶分析得到证实。分析了合成化合物(E)-3-((2-氧代-5-苯基呋喃-3(2H)-亚基)甲基)-4H-苯并吡喃-4-酮(3a)的分子几何结构，并与 X 射线衍射数据进行了比较，使用 6-311G 分裂价基函数进行了 DFT 计算。
Synthesis of (E)-3-{[2-oxo-5-arylfuran-3(2H)-ylidene]methyl}-4H-1-benzopyran-4-ones, crystal structure, quantum chemical substantiation.
A directed method for the preparation of hybrid compounds based on furan-2(3H)-ones and chromen-4(4H)-one, (E)-3-{[2-oxo-5-arylfuran-3(2H)-ylidene]methyl}-4H-1-benzopyran-4-ones, the structure of which was confirmed by elemental analysis, IR, UV, NMR spectroscopy, and X-ray single crystal analysis, was developed. The molecular geometry of the synthesized compound (E)-3-((2-oxo-5-phenylfuran-3(2H)-ylidene)methyl)-4H-chromen-4-one (3a) was analyzed and compared with X-ray diffraction data, DFT calculations were performed using 6-311G split-valence basis functions.
