An efficient of one-pot oxidative access to 3,4-dihydropyrimidin-2-(1H)-ones directly from aromatic alcs. under mild conditions is reported. The protocol involves 1-methylimidazolium hydrogen sulfate [Hmim]HSO₄ catalyzed oxidation of aromatic alcs. to aromatic aldehydes with NaNO₃ followed by their cyclocondensation with 1,3-dicarbonyl compounds and urea in the same reaction vessel at 80 °C within 2-4 h to afford 3,4-dihydropyrimidin-2-(1H)-ones in 55-97% overall yields.
