[Synthesis of 3-carbethoxi-2-phenyl-4-quinolones. Potential antimitotics]

The synthesis of the title compounds involved four main reactions: condensation between the acid chlorides and diethyl malonate to obtain the diethyl benzoylmalonates; transformation of these in diethyl chloroarylidenmalonates; the reaction of the substituted anilines with the chlorinated compounds and finally the thermal cyclization in diphenyl ether.
