target for therapeutic intervention, and the design of inhibitors of the protease may lead to the emergence of effective SARS-CoV-2-specific antivirals. We describe herein the results of our studies related to the application of X-ray crystallography, the Thorpe–Ingold effect, deuteration, and stereochemistry in the design of highly potent and nontoxic inhibitors of SARS-CoV-2 3CLpro.
α,α-Dideuterio benzyl alcohols are importantbuildingblocks for the synthesis of deuterium-labeled medicines and agrochemicals. We have developed the first general single-electron transfer reductive deuteration of readily commercially available aromatic esters for the synthesis of α,α-dideuterio benzyl alcohols using benign D2O and a mild single-electron donor SmI2. This operationally convenient method

alcohols under basic or neutral conditions without being affected by coordinative functional groups such as imidazole and tetrazole. Successful substrates for deuterium labelling include the pharmaceuticals losartan potassium, rapidosept, guaifenesin, and diprophylline. The deuterated losartan potassium shows higher stability towards the metabolism by CYP2C9 than the protiated analogue. Kinetic and DFT studies
化学选择性 C(sp 3 )-H 氘化的发展在合成化学中特别受关注。我们在此报告了使用氧化氘(D 2O) 作为主要氘源。该方法能够在碱性或中性条件下对伯醇和仲醇进行直接的化学选择性氘化,而不受咪唑和四唑等配位官能团的影响。用于氘标记的成功底物包括药物氯沙坦钾、rapidosept、愈创甘油醚和二丙茶碱。氘代氯沙坦钾对 CYP2C9 的代谢表现出比质子化类似物更高的稳定性。动力学和 DFT 研究表明,直接氘化通过醇脱氢生成羰基中间体,用 D 2将 [Ir III -H] 转化为 [Ir III -D] 进行O,将羰基中间体氘化,得到α-氘化产物。
