  摘要：

  An efficient synthesis of 2-aryl/heteroaryl substituted pyrimidinyl ethanones 4(a-t) was developed using a palladium-catalyzed Suzuki-Miyaura coupling reaction strategy. Use of Pd(OAc)(2) in the presence of PPh3 and Na2CO3 in 1,4-dioxane solvent was found to be the most effective reaction condition. (C) 2014 Elsevier Ltd. All rights reserved.

• Light-induced Free Radical Oxidation of 2-Oxo-1,2,3,4-tetrahydropyrimidines

  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.

• 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.
