## Abstract The Biginelli‐type condensation of ethyl acetoacetate/cycloketone, aldehyde and urea/thiourea under solvent‐free condition catalyzed by 10% gallium(III) iodide to form dihydropyrimidine‐2(1__H__)‐one derivatives was described. This process offered one way to constructing dihydropyrimidi
