A concise diastereoselective total synthesis of (−)-nakadomarin A has been completed in 21 steps from d-pyroglutamic acid. Key steps include an enecarbamate Michael addition/furan-N-acyliminium ion cascade cyclization to provide the tetracyclic core and ring-closing alkyne and alkene metatheses to construct the fifteen- and eight-membered azacycles, respectively.
由d-焦谷氨酸通过 21 个步骤完成了 (−)-nakadomarin A 的简明非对映选择性全合成。关键步骤包括烯氨基甲酸酯迈克尔加成/呋喃-N-酰亚胺离子级联环化以提供四环核心以及闭环炔烃和烯烃复分解反应以分别构建十五元和八元氮杂环。
