Abstract
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.
