  Synthesis of 2-substituted pyrimidines and benzoxazoles via a visible-light-driven organocatalytic aerobic oxidation: enhancement of the reaction rate and selectivity by a base

  摘要：

  利用有机光催化剂藻红Y双(四丁基铵盐)(TBA-藻红Y)和廉价氧化剂分子氧，已经实现了各种2-取代二氢嘧啶和酚亚胺的高效可见光驱动光催化氧化反应。在碱的辅助下，从底物二氢嘧啶或酚亚胺到TBA-藻红Y激发态的显著增强的光诱导电子转移，使得空气氧化能够选择性地生成2-(甲硫基)嘧啶或2-芳基苯并噁唑。

  An efficient visible-light-driven photocatalytic oxidation of various 2-substituted dihydropyrimidines and phenolic imines has been achieved using an organic photocatalyst eosin Y bis(tetrabutyl ammonium salt) (TBA-eosin Y) and inexpensive oxidant molecular oxygen. With the aid of a base, significantly enhanced photoinduced electron transfer from substrates dihydropyrimidines or phenolic imines to the excited state of TBA-eosin Y has enabled the aerobic oxidation to yield 2-(methylthio)pyrimidines or 2-arylbenzoxazoles selectively.
