A series of novel functionalized dihydroimidazo[2,1-a]isoquinolines and dihydroimidazo[2,1-a] quinolines were synthesized via the reaction between isoquinoline or quinoline derivatives and dialkyl acetylenedicarboxylates in the presence of 2-aminobenzothiazole in excellent yields. These novel synthesized compounds were suitably characterized by elemental analysis, Mass spectroscopy, IR, H-1-NMR & C-13-NMR spectra. In addition the compound (Z)-methyl 2-(1-(benzo[d]thiazol-2-yl)-2-oxo-1,2-dihydroimidazo[2,1-a]isoquinolin-3(10bH)-ylidene)acetate was subjected to the single crystal X-ray diffraction studies.
