  3,4-Dihydropyrimidin-2(1H)-ones were efficiently converted into the corresponding pyrimidin-2(1H)-ones in high yields within a short period of time on treatment with aqueous acetonitrile using 1,4-bis(triphenylphosphonium)-2-butene peroxodisulfate. Chemoselective oxidation of 3,4-dihydropyrimidin in the presence of other oxidizable functional groups was also achieved by this reagent.

  We describe the discovery and optimization of 3,4-dihydropyrimidin-2(1H)-ones as a novel family of (nonzanthine) A(2B) receptor antagonists that exhibit an unusually high selectivity profile. The Biginelli-based hit optimization process enabled a thoughtful exploration of the structure-activity and structure-selectivity relationships for this chemotype, enabling the identification of ligands that combine structural simplicity with excellent hA(2B) AdoR affinity and remarkable selectivity profiles.
