It′s a gas: A novel one‐pot process for the synthesis of α‐amino acids from imine equivalents using CO2 gas as a carbon source has been developed. This reaction was made possible by the reagent combination of TMSSnBu3 and CsF (see scheme). Three successive reactions (imine formation, stannylation, and carboxylation) proceeded in the same flask under these conditions to give products in up to 79 % yield
它是一种气体:已开发出一种新颖的单罐方法,该方法使用CO 2气体作为碳源,从亚胺当量合成α-氨基酸。通过TMSSnBu 3和CsF的试剂结合使该反应成为可能(参见方案)。在这些条件下,在同一烧瓶中进行了三个连续的反应(亚胺形成,甲氧基化和羧化),以最高79%的收率得到产物。Boc =叔丁氧羰基,TMS =三甲基甲硅烷基。
