N‐Dealkylation methods are well described for organic chemistry and the reaction is known in nature and drug metabolism; however, to our knowledge, enantioselective N‐dealkylation has not been yet reported. In this study, exclusively the (S)‐enantiomers of racemic N‐ethyl tertiary amines (1‐benzyl‐N‐ethyl‐1,2,3,4‐tetrahydroisoquinolines) were dealkylated to give the corresponding secondary (S)‐amines
N-脱烷基化方法在有机化学中已得到很好的描述,该反应在自然界和药物代谢中是已知的;然而,据我们所知,尚未报道对映选择性的N-脱烷基。在这项研究中,仅将外消旋N-乙基叔胺的(S)-对映体(1-苄基-N-乙基-1,2,3,4-四氢异喹啉)脱烷基得到相应的仲(S)-胺对映选择性的方式以牺牲分子氧为代价。该反应由小enzyme碱桥酶催化,该酶因形成CC键而闻名。以100mg规模证明了脱烷基作用,得到了光学纯的脱烷基产物(ee> 99%)。
