“…The synthesis of heterocyclic molecules has today become inevitable given its importance in human life. The biological interest [1,2,3] of these molecules is very broad and diversified. Several families of heterocyclic molecules are used as antiviral [4,5], anti tuberculosis [6,7], anti cancer [8,9,10], anti tuberculosis [11,12], anti malaria [13], anti fungus [14].…”

The identity of the 2-(4-Methyl-2-phenyl-4,5-dihydrooxazol-4-ylmethyl)-isoindole-1,3-dione, previously synthesized in our laboratory, was proven without doubt by means of 1D and 2D NMR spectroscopy. Two-dimensional NMR spectroscopy played a major role. The analysis of the 2D-COSY spectrum of isoindoline-1,3-dione derivative shows a perfect correlation between neighboring protons. Thus, a correlation was noted between the protons of the phthalimide, H(8) and H(9) on the one hand and H(8') and H(9') on the other hand. The analysis of the 2D-HSQC spectrum of the studied compound indicates a faultless correlation between protons and adjacent carbons, and no correlation in the case of all quaternary carbons.
