  A copper-catalyzed alkene transfer hydrodeuteration reaction that selectively incorporates one hydrogen and one deuterium atom across an aryl alkene is described. The transfer hydrodeuteration protocol is selective across a variety of internal and terminal alkenes and is also demonstrated on an alkene-containing complex natural product analog. Beyond using 1H, 2H, and 13C NMR analysis to measure reaction

  描述了一种铜催化的烯烃转移加氢氘化反应，该反应选择性地将一个氢和一个氘原子结合到芳基烯烃上。转移加氢氘化协议对各种内部和末端烯烃具有选择性，并且还在含烯烃的复杂天然产物类似物上得到了证明。除了使用1 H、2 H 和13C NMR 分析测量反应选择性，六转移氢化氘化产物通过分子旋转共振 (MRR) 光谱分析。通过与高通量样品分析兼容的测量方法，进一步探索了 MRR 光谱在氘化学中同位素杂质分析中的应用。在第一步中，使用宽带啁啾脉冲傅立叶变换微波光谱仪分析反应化学中所有同位素变体的 MRR 光谱特征。有了签名，就可以创建测量脚本，使用商用腔增强 MRR 光谱仪对样品成分进行定量分析。使用该仪器的样品消耗量低于 10 毫克，分析时间约为 10 分钟 - 与宽带 MRR 光谱相比，两者都代表了数量级的减少。迄今为止，这些测量代表了转移加氢氘化反应中选择性的最精确的光谱测定，并确认在这种温和的协议下可以实现

  demonstrated by conducting a series of selective reductions of alkynes and alkenes, and hydrogen–deuterium exchange reactions using two‐chamber reactors. Finally, as the water reduction reaction generates an intermediate borohydride species, a range of aldehydes and ketones were reduced by using water as the hydride source.

  2-(2-Aminoethoxy)-1-hydroxyethyl derivatives of bicyclic arenes) naphthalene, thianaphthene, benzofuran, and indole) were prepared and screened for antiamnestic (AA) and antihypoxic (AH) activities which were evaluated by measuring the reversing potency in electroconvulsion-induced amnesia and the protective effect against hypoxia, respectively, in mice. Compound 3o, 1-(benzo[b]thiophen-5-yl)-2-(2-diethylaminoethoxy)ethanol, showed the best AA and AH activity profile, being superior to our prototype compound, 2-(2-dimethylaminoethoxy)-1-phenylethanol (1). Elongation of the ethylene linkage in the side chain of 3o to 3- and 4-carbon moiethies brought about a significant decrease in AH activity. Compound 3o was further investigated for its protective effect against Co2-induced memory impairment and for acute toxicity in mice. It is ten-fold more potent than tacrine in the amnesia-reversal assay and is considerably less toxic than tacrine.
