Carbocyclinone-534 is a new antibiotic produced after the metabolism of tapinarof. We identify a biomimetic total synthesis of carbocyclinone-534 in eight steps by taking advantage of an intermolecular Diels-Alder homodimerization/dehydrogenation/intramolecular Diels-Alder cycloaddition cascade. This synthetic sequence provides direct experimental evidence for revealing the biosynthetic pathway of carbocyclinone-534.
碳环酮-534 是经过他卡西醇代谢后的一种新型抗生素。我们通过利用分子间 Diels-Alder 同二聚化/脱氢/分子内 Diels-Alder 环加成级联反应,以八步反应实现了碳环酮-534 的仿生全合成。该合成序列为揭示碳环酮-534 的生物合成途径提供了直接的实验证据。
