Amino acid derivatives undergo non-Kolbe electrolysis to afford enantiomerically enriched α-alkoxyamino derivatives through intermediate chiral carbenium ions. The products contain N,O-acetals which are important structural motifs found in bioactive natural products. The reaction is performed in a continuous flow electrochemical reactor coupled to a 2D-HPLC for immediate online analysis. This allowed
氨基酸衍生物经过非Kolbe电解,通过中间体手性碳正离子得到对映体富集的α-烷氧基氨基衍生物。产品含有N,O-乙缩醛,这是生物活性天然产品中的重要结构基序。该反应在与2D-HPLC相连的连续流电化学反应器中进行,以立即进行在线分析。这样可以通过DoE方法快速筛选温度,电极材料,电流,流速和浓度。与在线HPLC的结合表明,通过将流电化学与多维分析相结合,立体选择性反应也可以从极大加速的优化中受益。
