چکیده
|
Fe3o4 bonded pyridinium-3-carboxylic acid-n-sulfonic acid chloride, as a magnetic and reusable catalyst, was reported for the one-pot multi-component synthesis of some 3,4-dihydropyrimidin-2(1h)-ones by the reaction of urea, ethyl acetoacetate and various aldehyde under solvent-free conditions. the products were identified by ft-ir, 1h nmr and 13c nmr spectra and the catalyst was reused successfully for three times.
