Oxo-2-polyfluoroalkylethane-1-sulfones and -sulfamides undergo Biginelli reaction with aryl aldehydes and (thio)urea to give 4-hydroxy-4-polyfl uoroalkyl-5-sulfonyl-6-aryl- tetrahydropyrimidin-2(1 H)-(thi)ones, whereas three-component reaction with urea and trialkyl orthoformate provides 4-hydroxy-4-polyfluoroalkyl-5-sulfonyl-3,4-dihydropyrimidin-2(1 H)- ones. Some chemical properties of the synthesized
