Abstract | ||||
The chemical reactivity of diketone 1 toward some nucleophilic and electrophilic reagents was investigated. diketone 1 was used as a key precursor for the synthesis of many important heterocyclic compounds. The synthesized compounds were characterized by IR, 1H-NMR, MS spectral and elemental analysis. | ||||
