  A traceless polymer-supported synthesis of 4-benzoylquinazolines was developed using the following commercially available building blocks: Fmoc-α-amino acids, 2-nitrobenzensulfonyl chlorides and α-bromoacetophenones. The acyclic intermediates underwent base-catalyzed rearrangement involving C–C and N–N bond formation followed by ring expansion and yielded resin-bound dihydroquinazoline-2-carboxylic

  使用以下可商购的构件开发了无痕聚合物支持的4-苯甲酰基喹唑啉合成方法：Fmoc-α-氨基酸，2-硝基苯磺酰氯和α-溴乙酰苯。无环中间体经历了碱催化的重排，涉及C–C和N–N键的形成，随后发生环扩展并产生了与树脂结合的二氢喹唑啉-2-羧酸。通过三氟乙酸处理将它们从树脂中释放后，碱介导的脱羧反应以中等至高收率和纯度产生了目标喹唑啉。

  When a mixture of 4-chloroquinazoline (7), an aromatic aldehyde 6, sodium hydride, and a catalytic amount of 1, 3-dimethylbenzimidazolium iodide (1) in tetrahydrofuran (THF) was refluxed with stirring for an appropriate time, the chlorine atom of 7 was replaced with the aroyl group, and the 4-aroylquinazolines 10 were obtained in excellent yields. Similar treatments of 4-chloro-2-methylquinazoline (8) and 4-chloro-2-phenylquinazoline (9) led to the 4-aroyl-2-methylquinazolines 11 and the 4-aroyl-2-phenylquinazolines 12, respectively.Use of N, N-dimethylformamide (DMF) instead of THF as the reaction solvent in the above reaction reduced the reaction time and increased the yields of the ketones 10 and 12 as compared with those in THF.

  当4-氯喹唑啉（7）、芳香醛6、氢化钠和催化量的1,3-二甲基苯并咪唑碘化物（1）在四氢呋喃（THF）中搅拌回流适当时间后，7中的氯原子被芳酰基取代，得到产率极佳的4-芳酰基喹唑啉10。类似地处理4-氯-2-甲基喹唑啉（8）和4-氯-2-苯基喹唑啉（9），分别得到4-芳酰基-2-甲基喹唑啉11和4-芳酰基-2-苯基喹唑啉12。在上述反应中使用N,N-二甲基甲酰胺（DMF）而非THF作为反应溶剂，相比THF，可以缩短反应时间并提高酮10和12的产率。

  The ability of 1, 3-dimethylimidazolium iodide (1) to catalyze the aroylation of the chloroheteroarenes 4-8 with arenecarbaldehydes 3 as sources of the aroyl groups was examined in order to develop a preparative method of aroylheteroarenes. In the presence of 1, the treatment of the 4-chloroquinazolines (4 : 2-H, 5 : 2-Me, 6 : 2-Ph) with arenecarbaldehyde 3 in refluxing THF (tetrahydrofuran) or dioxane led to the 4-aroylquinazolines (9 : 2-H, 10 : 2-Me, 11 : 2-Ph) in excellent yields, as had been found with 1, 3-dimethylbenzimidazolium iodide (2). Similar reaction of the 4-chloro-1H-pyrazolo[3, 4-d]pyrimidines (7 : 1-Ph, 8 : 1-Me) with arenecarbaldehyde 3 yielded the corresponding 4-aroyl-1H-pyrazolo[3, 4-d]pyrimidines (12 : 1-Ph, 13 : 1-Me). Compound 1 seems to catalyze the aroylation of a wider range of arenecarbaldehydes 3 as compared with 2.

  研究了1,3-二甲基咪唑锭碘化物（1）催化氯杂芳烃4-8与芳烯羰基化合物3的芳酰基化反应的能力，以开发一种合成芳酰杂芳烃的新方法。在存在1的条件下，4-氯喹唑啉（4：2-H，5：2-Me，6：2-Ph）与芳烯羰基化合物3在回流的THF（四氢呋喃）或二噁烷中反应，得到了优良产率的4-芳酰喹唑啉（9：2-H，10：2-Me，11：2-Ph），这与1,3-二甲基苯并咪唑锭碘化物（2）得到的结果一致。类似地，4-氯-1H-吡唑[3,4-d]嘧啶（7：1-Ph，8：1-Me）与芳烯羰基化合物3反应，得到了相应的4-芳酰-1H-吡唑[3,4-d]嘧啶（12：1-Ph，13：1-Me）。与2相比，化合物1似乎能催化更广泛的芳烯羰基化合物3的芳酰基化反应。

  An efficient and selective Pd(0)-catalyzed sp3 C–H bond arylation–oxidation of 4-methylquinazolines is reported. The method enables the introduction of arylketone at the benzylic position of 4-methylquinazolines without the use of an additional directing group, and atmospheric oxygen is used as the sole oxidant.
