Ll. Wu et al., One pot synthesis of 3-substituted-(1H)-pyrimidin[1,2-a] quinoline-1-ones under microwave irradiation, CHEM J CH U, 21(12), 2000, pp. 1867-1869
2-Aminoquinoline reacted with 5-bismethylthiomethylene or 5-methylthioalkyl
idene isopropylidene malonates under microwave irradiation as one pot react
ion to afford a new convenient synthesis of 3-substituted-1(1H)-pyrimidine
[1,2-a] quinoline-1-ones.
