A simple,
efficient and green procedure has been developed for the synthesis of
dihydropyrimidinones (Products of Biginelli) using phosphate fertilizers (mono-ammonium
phosphate (MAP), di-ammonium phosphate (DAP) and triple super phosphate (TSP))
as catalyst. The one-step reaction involved the three compounds, which are
registered aromatic aldehydes, dicarbonyl compounds and the urea/thiourea. This
new method provides some advantages such as obtaining excellent yields (98%),
as well as the short duration of the reaction, which may attain 2 min. These
catalytic heterogeneous systems present also the advantage of being easily
recycled.
