This article describes a concise synthesis of lysergic acid from simple aromatic precursors. The successful strategy relies on the coupling, dearomatization, and cyclization of a halopyridine with a 4-haloindole derivative in 6 total synthetic steps from commercial starting materials. In addition to highlighting the advantages of employing dearomative retrosynthetic analysis, the design is practical
本文介绍了从简单的芳香族前体简明合成麦角酸。成功的策略依赖于卤代吡啶与 4-卤代吲哚衍生物的偶联、脱芳构化和环化,总共需要 6 个合成步骤,从商业原料开始。除了突出采用脱芳烃逆合成分析的优势外,该设计是实用的,预计能够合成新型神经活性化合物,例如新型天然产物衍生物 12-氯麦角酸的合成。
