Alkylation of ethyl 2-(4-oxo-1,4-dihydroquinolin-2-yl)acetate by Michael addition with various alkenes has been carried out. The C-alpha alkylated intermediates so formed can be cyclized with hot polyphosphoric acid to acridine-1,9-diones.
New syntheses of acridin-9-ones, benzo[c]quinolizin-6-ones, pyrrolo[1,2-a]quinoline-1,5-diones, and some related tetracyclic compounds
