5-a]pyridine-1-carboxylic acids. By using the reaction of 2-(aminomethyl)pyridine with acyl chlorides followed by one-pot treatment with trifluoroacetic anhydride, 2,2,2-trifluoro-1-imidazo[1,5-a]pyridin-1-ylethanones were obtained, which were then converted into imidazo[1,5-a]pyridine-1-carboxylic acids in high preparative yields through haloform cleavage. We report a novel and efficient approach to the synthesis
摘要 我们报告了一种新型的合成咪唑并[1,5 - a ]吡啶-1-羧酸的有效方法。通过使2-(氨基甲基)吡啶与酰氯反应,然后用三氟乙酸酐一锅处理,得到2,2,2-三氟-1-咪唑并[1,5 - a ]吡啶-1-丙酮酮,然后通过卤代形式裂解以高制备产率将其转化为咪唑并[1,5 - a ]吡啶-1-羧酸。 我们报告了一种新型的合成咪唑并[1,5 - a ]吡啶-1-羧酸的有效方法。通过使2-(氨基甲基)吡啶与酰氯反应,然后用三氟乙酸酐一锅处理,得到2,2,2-三氟-1-咪唑并[1,5 - a ]吡啶-1-丙酮酮,然后通过卤代形式裂解以高制备产率将其转化为咪唑并[1,5 - a ]吡啶-1-羧酸。
