  Photoinduced Single Electron Transfer on 5-Aryl-1,2,4-oxadiazoles:  Some Mechanistic Investigations in the Synthesis of Quinazolin-4-ones

  摘要：

  The photochemistry of some 5-aryl-3-methoxy- (or 5-aryl-3-phenyl-) 1,2,4-oxadiazoles irradiated in the presence of different sensitizers [such as diphenylacetylene (DAC), 9,10-diphenylanthracene (DAN), or triphenylene (TPH)] or ground-state donors such as triethylamine (TEA) has been investigated. Intermediates arising from breaking of the ring O-N bond develop both into quinazolin-4-ones (by a heterocyclization reaction involving the aryl at the C-5 of the oxadiazole nucleus) and into open-chain products (corresponding to a reduction at the ring O-N bond), in different ratios depending on their structures and photoreaction conditions. A reasonable explanation considers sensitization by photoinduced electron transfer either from the sensitizer in its excited state to the oxadiazole in its ground state or from the electron donor reagent (TEA) to the excited oxadiazole; in both cases an oxadiazole radical anion is formed as a key species from which breaking of the ring O-N bond takes place. Reduction potentials of representative oxadiazoles confirm this hypothesis. Possible applications in the synthesis of variously substituted quinazolin-4-ones are recognized.

  present reaction conditions. In this tandem approach, involvement of transfer hydrogenation of the nitro functionality with in situ generated ammonia, imination, nitrile hydration to amide and oxidative cyclization sequences have been established. The process avoids the use of an external hydrogen source, costly catalysts as well as the isolation of amine and amide intermediates.

  通过邻位取代的硝基芳烃，首次实现了铁（III）氯化铁催化的苯甘氨酸的脱羧脱氨基官能化反应，从而合成了4（3 H）-喹唑啉酮和苯并咪唑。在甲苯中以碳酸钾为碱存在下，于120°C下，2-硝基苯甲腈/ 2-硝基N，N-二苯胺与苯基甘氨酸反应生成的产物收率为45-87％。在本反应条件下，各种官能团如硝基，氟，氯和三氟甲基被很好地耐受。在这种串联方法中，涉及硝基官能团的转移氢化与原位反应已经确定了生成的氨，亚胺化，腈水合成酰胺和氧化环化顺序。该方法避免了使用外部氢源，昂贵的催化剂以及胺和酰胺中间体的分离。
