    摘要:
    一系列4-取代的5-乙酰基和5-羧乙酯基-2-氧代-1,2,3,4-四氢嘧啶在紫外辐射下在有或无苯甲酰过氧化物存在下被氧化。杂环环上4-和5-位置的取代基的性质影响光氧化的速率,这些化合物在有苯甲酰过氧化物存在下的照射显著减少了反应时间。在速率决定步骤中,苯甲酰氧自由基去除4-H形成三氢嘧啶基自由基中间体。这种苄基和烯丙基自由基中间体的稳定性受到苯基团上附加取代基的性质和位置的影响,该苯基团位于C-4。

    A variety of Biginelli 5-acetyl-3,4-dihydropyrimidin-2(1H)-ones are efficiently oxidized to their corresponding pyrimidin-2(1H)-one derivatives upon UV irradiation under argon atmosphere in chloroform solution. The nature of the additional substituent on the phenyl ring located on C-4 of the heterocyclic ring influences the rate of reaction. An electron-transfer induced photoreaction is proposed based

  • Free-radical oxidation of 1,2,3,4-tetrahydro-2-oxopyrimidines
    作者:Hamid Reza Memarian、Nazanin Jafarpour、Asadallah Farhadi
    DOI:10.1007/s00706-011-0573-8
    日期:2012.2
    Free-radical oxidation of 4-substituted 5-acetyl- and 5-carboethoxy-1,2,3,4-tetrahydro-2-oxopyrimidines using benzoyl peroxide under thermal conditions has been investigated to elucidate the effects of the nature of the substituents in the 4- and 5-positions on the rate of reaction. Whereas the presence of the acetyl group instead of the carboethoxy group in position 5 decreases the rate of oxidation, the nature of the additional substituent (electron-releasing or electron-withdrawing group) and also its location on the phenyl ring attached to C-4 of the tetrahydropyrimidinone ring effectively influence the rate of reaction. The latter observation supports the proposal that the removal of the 4-hydrogen on the heterocyclic ring occurs in the rate-determining step.
  • Ultrasound-assisted dehydrogenation of 5-acetyl-3,4-dihydropyrimidin-2(1H)-ones
    作者:Hamid Reza Memarian、Asadollah Farhadi、Hassan Sabzyan

    日期:2010.3
    In this study, various 5-acetyl-3,4-dihydropyrimidin-2(1H)-ones were synthesized and the dehydrogenation of these compounds by potassium peroxydisulfate in aqueous acetonitrile under thermal and sono-thermal conditions were investigated. Whereas the effect of the nature of 4-substituent influences the rate of reaction, the application of sonic waves decreases drastically the time of thermal reaction. (c) 2009 Elsevier B.V.
