AbstractAn efficient synthesis of 3,4-dihydropyrimidin-2-(1H)-one derivatives by one-pot three-component condensation reaction between an alkyl or aryl aldehyde, a 1,3-dicarbonyl compound, and urea or thiourea in the presence of catalytic amount of bromodimethylsulfonium bromide has been developed. The condensation product was obtained in excellent yields in refluxing ethanol and easily separated from the reaction mixture and purified.

An investigation of base promoted reaction of phenylanthranilate and isocyanate has been carried out. The reaction between phenylanthranilate (11) and phenylisocyanate and n-butylisocyanate gave remarkable yields of corresponding 1,3-Benzo-diazine-2,4-diones (12a) and (12b).   Keyword: one-pot synthesis, heterocyclic compound
