We report the first example of catalytic asymmetric direct amination of α-monosubstituted nitroacetates using di-tert-butyl azodicarboxylate. The simple and easily available Hatakeyama's catalyst β-ICD 11 was found to be a highly enantioselective catalyst for this reaction.
我们首次报道了使用
偶氮二甲酸二叔丁酯催化δ-单取代硝基
乙酸酯的不对称直接胺化反应。研究发现,简单易得的 Hatakeyama 催化剂 δ-ICD 11 是该反应的高对映选择性催化剂。
