A convenient synthetic method for substituted 2,5-dioxo-1,2,3,4,5,6,7,8-octahydroquinolines is described. Heating Meldrum's acid, dimedone, ammonium acetate and different aromatic aldehydes without a solvent in a microwaveirradiation for 2–5 minutes affords 4 in 72–86% yield. The structure of these compounds has been thoroughly studied by x-ray crystallographic analysis.
