The asymmetric synthesis of the antibacterial natural product, streptophenazine G, has been achieved by employing asymmetric alkylation and asymmetric aldol reactions using chiral oxazolidinones as the key steps. The originally proposed structure for streptophenazine G has been revised, and its absolute configuration has been determined to be 1′S,2′R,6′S. The asymmetric total synthesis of 6′-epi-streptophenazine
通过使用手性恶唑烷酮作为关键步骤,采用不对称烷基化和不对称醛醇缩合反应,可以实现抗菌天然产物链霉吩嗪G的不对称合成。最初提议的链脲吩嗪G的结构已被修改,其绝对构型已确定为1 'S,2'R,6 'S。还描述了6'-表位-streptophenazine G的不对称全合成。
