[structure: see text] The first total synthesis of anachelin H is reported. Starting from L-Ser, a stereodivergent synthesis of the polyketide fragment resulting in all possible diastereoisomers is described. The alkaloid peptide fragment is prepared via a tellurium-mediated oxidative aza annulation as the key step. Coupling of the fragments gave synthetic anachelin H, which was found to be identical to a sample
[结构:见正文]报道了安那林H的第一个全合成。从L-Ser开始,描述了导致所有可能的非对映异构体的聚酮化合物片段的立体发散合成。通过碲介导的氧化氮杂环化法制备生物碱肽片段是关键步骤。片段的偶联产生了合成的安那奇林H,其与天然产物的样品相同,因此通过全合成证实了构型。
