  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).
