[image omitted] An efficient, solvent-free, one-pot, three-component cyclocondensation reaction between aldehyde, ketone, and urea to give 4,6-diarylpyrimidin-2(1H)-ones (DAPMs) using iodine as catalyst is described. This new protocol provides a simple and environmentally benign route along with the associated advantages of good to excellent yield of the products (90-96%) and short reaction times (5-15min) at 80 degrees C.
