| Description |
567-575
Several novel 3-arylidene-5-(4-methoxy-3-nitrophenyl)-2(3<em>H</em>)-furanones (<strong>2a-d</strong>) have been successfully prepared and used as precursors for building up of other new heterocyclic architectures such as pyrrolones (<strong>4a-c</strong>), (<strong>5</strong>) and unsaturated aroyl-hydrazides <strong>(7a-d)</strong>. These aroyl-hydrazides have been subsequently converted into pyridazinone derivatives <strong>(8a-d)</strong> by refluxing in HCl/AcOH mixture. Eventually, benzoylation of the hydrazides (<strong>7a-c</strong>) with benzoyl chloride affords the corresponding N-benzoyl-3(2<em>H</em>)-pyridazinones (<strong>9a-c</strong>). The structures of all synthesized compounds have been established using elemental analysis and spectral methods. The photophysical (fluorescence and electronic absorption spectra) properties of newly synthesized compounds have also been investigated. |
