  • Light-induced Free Radical Oxidation of 2-Oxo-1,2,3,4-tetrahydropyrimidines
    作者:Hamid Reza Memarian、Leila Hejazi、Asadallah Farhadi
    DOI:10.1515/znb-2012-0313
    日期:2012.3.1

    A variety of 4-substituted 5-acetyl- and 5-carboethoxy-2-oxo-1,2,3,4-tetrahydropyrimidines were oxidized under UV irradiation in the presence or absence of benzoyl peroxide. The nature of the substituents on the 4- and 5-positions of the heterocyclic ring affects the rate of photo-oxidation, and irradiation of these compounds in the presence of benzoyl peroxide decreases the time of reaction drastically. Removal of 4-H by a benzoyloxy radical under formation of a trihydropyrimidinoyl radical intermediate occurs in the rate-determining step. The stability of this benzylic and allylic radical intermediate is affected by the nature and the position of the additional substituent on the phenyl group located at C-4.

    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。

  • 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.
  • Light-induced dehydrogenation of 3,4-dihydropyrimidin-2(1H)-ones
    作者:Hamid Reza Memarian、Asadollah Farhadi
    DOI:10.1007/s00706-009-0156-0
    日期:2009.10
    UV light irradiation of Biginelli 3,4-dihydropyrimidin-2(1H)-ones in chloroform in an argon atmosphere leads to dehydrogenation of these compounds to their corresponding pyrimidin-2(1H)-ones in excellent yields. Irradiation in the same solvent under an oxygen atmosphere generates, in addition, various hitherto unidentified products. A light-induced electron transfer from the substrate to the solvent is proposed as the initial event, supported by the detection of dichloromethane and hydrogen chloride in the photolysate.
