The first total synthesis of the monoamine oxidase inhibitors chaetoquadrins A-C has been accomplished. Key steps in the synthesis include an aromatic Claisen rearrangement, asymmetric boron aldol reaction and acid-mediated spiroketalization. Comparison of spectral data for the synthetic spiroketals confirmed the proposed structure for these natural products.
已完成单胺氧化酶抑制剂 chaetoquadrins A-C 的首次全合成。合成中的关键步骤包括芳香族 Claisen 重排、不对称硼醇醛缩合反应和酸介导的螺缩酮化反应。对合成螺缩酮的光谱数据进行比较,证实了这些天然产物的结构。
