The reaction of phthalaldehyde, ammonium acetate and dialkyl acetylenedicarboxylates in the presence of phenyl isocyanate derivatives to proceeded at room temperature and under mild conditions to afford synthesis of dialkyl-۱-(۴-(alkyl)phenyl)-۲-oxo- ۱,۱۱b-dihydro-۲H-pyrimido[۲,۱-a]isoquinoline-۳,۴-dicarboxylate derivatives in excellent yields. All products were established by IR, ۱H, ۱۳CNMR, Mass spectroscopy and elemental analysis.
کلمات کلیدی: Phthalaldehyde, Dialkyl acetylenedicarboxylates, Multicomponent reaction.
