چکیده انگلیسی
Six new isoflavone-based esters, 7-decanoyloxy-3-(4â²-substitutedphenyl)-4H-1-benzopyran-4-ones, derived from 1,3-benzenediol (resorcinol) and different para substituted phenylacetic acids have been synthesized and characterized. The 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-(4â²-methylphenyl)-4H-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 title compound also revealed that the two phenyl rings of the central moiety were planar whilst the heterocyclic ring was found to pucker slightly from the mean plane.
