with aqueous H(D)Cl in an undivided cell, aliphatic and aromatic aldehydes and ketones undergo deoxygenative hydrogenation and deuterization to give hydrocarbons and deuterocarbons. The general features of this transformation are: 1) H+/D+ as the sources of H/D; 2) mild reaction conditions (room temperature, open flask, CH3CN and water as cosolvent); 3) easily scaled-up to 100 grams. A series of D-labeled
我们在此报告修改后的 Clemmensen 还原。当在未分隔的电池中与 H(D)Cl 水溶液反应时,脂肪族和芳香族醛和酮会发生脱氧氢化和氘化反应,生成烃类和氘代烃。这种转化的一般特征是: 1)H + /D +作为H/D的来源;2)温和的反应条件(室温,开口烧瓶,CH 3 CN和水作为共溶剂);3) 轻松放大至 100 克。通过该方法合成了一系列D标记的药物。
