  Synthesis and Reactivities of 1,3-Dimethyl-2-(a-hydroxybenzyl)imidazolium and 1,3-Dimethyl-2-(a-hydroxybenzyl)benzimidazolium Iodides

  摘要：

  1,3-Dimethyl-2-(alpha-hydroxybenzyl)benzimidazolium iodide (3a) was synthesized from 1-methylbenzimidazole (10) through two steps involving lithiation and quaternization. Treatment of 3a with 4-chloro-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine (6) afforded 4-benzoyl-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine (15a). 4-Benzoylquinazoline (14a) and 7-benzoyl-3-phenyl-3H-1,2,3-triazolo[4,5-d]pyrimidine (16a) were given by reaction of 3a with 4-chloroquinazolin (5) and 7-chloro-3-phenyl-3H-1,2,3-triazolo[4,5-d]pyrimidine. (7). Treatment of 3a with benzaldehyde (9a) gave benzoin (8a). Similar results were obtained in the reactions of 1,3-dimethyl-2-(alpha-hydroxybenzyl)imidazo iodide (4a).

  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。
