Abstract

The reaction of substituted methyl aroylpyruvates  with 1-aminomethyl-1,2,3,4-tetrahydroisoquinoline dihydrochloride in the presence of AcOH gives 3-aroylmethylene-1,6,7,11b-tetrahydro-2H-pyrazino[2,1-a]isoquinolin-4-ones whose structures have been confirmed by IR, 1H NMR, and mass spectrometry.
