Methods for regioselective N-trideuteromethylation of tautomeric polyaza heterocycles are highly sought-after. Disclosed herein is an N-trideuterated methylation reaction of imidazoles and pyrazoles with high regioselectivity and deuterium purity using easily available CF3SO3CD3 as the –CD3 source. This method enables the easy synthesis of important deuterium-labeled azoles, including dimetridazole-d3
互变多氮杂环的区域选择性N-三十二甲基化方法备受追捧。本文公开了使用容易获得的CF 3 SO 3 CD 3作为-CD 3源的具有高区域选择性和氘纯度的咪唑和吡唑的N-三氘化甲基化反应。该方法可以轻松合成重要的氘标记唑类化合物,包括二甲硝唑- d 3 、异硝唑- d 3 、羟基二甲硝唑- d 3和罗硝唑- d 3 。
