  摘要：

   介绍 氘化分子在生命科学中具有几个关键应用，最显着的是在吸收、分布、代谢、排泄和毒性 (ADMET) 研究中， 1 ，而且还通过利用动力学同位素效应进行机械研究（方案1A）。 2, 3 最近，掺入氘已被用作改变药物代谢特征的策略，例如 Austedo 和 Deucravacitinib，这是 FDA 批准的前两种氘化药物化合物（方案 1B）。 4, 5 氢同位素、氘（ 2 H 或 D）和氚（ 3 H 或 T）的广泛使用在很大程度上是由于这些同位素体的合成可及性方面取得了进展。特别是，通过氢同位素交换 (HIE) 6, 7 安装允许在后期掺入氘或氚，并避免使用昂贵的标记底物或试剂进行耗时的重新合成。在我们的实验室中，一系列富电子、空间位阻的铱 (I) NHC/膦催化剂已能够使用各种导向基团（方案 1C）、 8, 9 和包括具有挑战性的芳基磺酰胺 10 和N-杂环。 11 重要的是，此类催化剂在温和条件下促进

  A new LiI-promoted O- to N-alkyl migration has been developed for the conversion of O-alkylated 2-hydroxy pyridines, quinolines, and pyrimidines to the corresponding N-alkylated heterocycles in good to excellent yields (57−99%). This method serves as an efficient means for the preparation of N-benzyl pyridones, quinolones, and pyrimidones.

  DOI：10.1055/s-2005-921898

  日期：——

  2-Benzyloxy-1-methylpyridinium triflate (Bn-OPT) effects the benzylation of alcohols in the absence of acidic or basic promoters. Solutions of Bn-OPT and primary, secondary, or tertiary alcohols give rise to the corresponding benzyl ethers upon mild heating. Acid scavengers are generally included in the reaction mixture. Bn-OPT is crystalline and bench-stable.

  2-苄氧基-1-甲基吡啶三氟甲磺酸盐（Bn-OPT）在无需酸性或碱性促进剂的情况下，实现醇的苄基化反应。Bn-OPT溶液与伯醇、仲醇或叔醇在温和加热条件下生成相应的苄基醚。通常在反应混合物中加入酸清除剂。Bn-OPT为晶体且具有实验室稳定储存的特性。
