Electrochemical oxidation was performed during the organocatalyzed α-oxyamination of aldehydes by using a one-compartment electrolytic cell under galvanostatic conditions. In the presence of substoichiometric amounts of sec-amines, the desired coupling products were formed in good yield. The asymmetric variant of the α-oxyamination of aldehydes was examined by using chiral sec-amines. Control experiments
通过在恒电流条件下使用单室电解池在醛的有机催化 α-氧胺化过程中进行电化学氧化。在亚化学计量量的仲胺存在下,所需的偶联产物以良好的产率形成。通过使用手性仲胺检查醛的 α-氧胺化的不对称变体。对照实验和循环伏安法证实该反应的关键中间体是衍生自仲胺催化剂和醛的烯胺的阳离子自由基。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
