Elansolid A is a structurally complex polyketide macrolactone natural product that exhibits promising antibacterial properties. Its challenging asymmetric totalsynthesis was achieved by a convergent strategy, in which the tetrahydroindane core of the molecule and an eastern vinyl iodide moiety were combined as the main fragments. The central tetrahydroindane motif was constructed with high stereoselectivity
Elansolid A 是一种结构复杂的聚酮化合物大环内酯天然产物,具有良好的抗菌性能。其具有挑战性的不对称全合成是通过收敛策略实现的,其中分子的四氢茚满核心和东部碘乙烯部分结合为主要片段。通过仿生分子内 Diels-Alder 环加成,以高立体选择性构建中心四氢茚满基序,一步生成四个立体中心。这一关键步骤的立体控制可以通过在基板上临时引入空间定向碘取代基产生的 1,3-烯丙基应变来实现。完成合成的大环内酯基序的形成是通过两种不同的逆合成断开实现的,即,
