Naphthalene Benzimidazole Derivatives: Syntheses and Structure Confirmations

The naphthalene benzimidazole (NBI) with 1 and 4 monosubstituted derivatives 1-4 were synthesized and purified. The structure of compound 1 was analyzed in detail by using UV, IR, MS, 1H NMR, 13C NMR, DEPT, 1H-13C HSQC, 1H-13C HMBC techniques, and the positions of 1H and 13C NMR peaks of the derivatives were assigned. Quantum calculations were also applied by GIAO and CSGT methods to calculate the NMR shifts of NBI derivatives. The structure of the compounds were confirmed by various spectral techniques.
