Abstract
An eco-friendly, highly efficient, and tandem reaction between 2-hydroxy-1,4-naphthoquinone and quinolinium salts in the presence of DABCO, 1,4-diazabicyclo[2.2.2]octane, in aqueous medium is developed for the synthesis of functionalized polycyclic naphthooxazocines. The advantageous features of this operationally simple procedure along with good to excellent yields of products highlighted this method for the preparation of oxazocine. Moreover, the products obtained without the need to column chromatography. In order to reduce the hazards of chemicals and solvents, the reaction was conducted in the green solvent, water. All newly synthesized compounds were characterized by different methods involving IR, 1H NMR, 13C NMR spectroscopy.
