  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。

  A simple and environmentally friendly synthesis was developed for the preparation of 2-arylimidazoline derivatives and 2-arylbenzoxazole derivatives using a small pore size zeolite. The similar reaction was not applicable to the preparation of the sulfur-containing analogs cysteamine or 2-aminothiophenol, probably because of a disadvantageous reaction between the zeolite and the thio compound. © 2004

  Eosin Y-catalyzed one-pot coupling and cyclization of o-substituted anilines with aldehydes to form benzoxazoles and benzothiazoles under mild condition has been developed. The reaction scope was broadly tolerant of various 2-substituted anilines and aldehydes. The desired products were obtained in high yields with the use of eosin Y as a photocatalyst under a substantial refinement of reaction conditions
