The selective synthesis of various dideuterochalcones as potentially bioactive deuterium-labeled products is presented, by means of the highly controlled partial deuteration of antidiabetic chalcone derivatives. The benefits of continuous-flow processing in combination with on-demand electrolytic D2 gas generation has been exploited to avoid over-reaction to undesired side products and to achieve selective
通过高度控制的抗糖尿病查尔酮衍生物的部分氘代化,提出了各种可能的具有生物活性的氘代标记产物的二氘代十二烷的选择性合成。连续流处理与按需电解D2气体生成相结合的优势已得到利用,可避免对不良副产物的过度反应,并在不需要烯键的碳-碳双键的情况下实现选择性氘加成非常规催化剂或昂贵的特殊试剂。事实证明,压力,温度和停留时间的作用对于微调产物选择性和反应速率之间的敏感平衡至关重要。提出的基于流化学的氘化技术缺少经典批处理方法的大多数缺点,
