(−)-retigeranic acid A was described, which relies on a crucial reductive skeletal rearrangement cascade for the controllable assembly of diverse angular triquinane subunits. Taken together with an intramolecular Michael/aldol cyclization, an ODI-[5 + 2] cycloaddition/pinacol rearrangement cascade, a Wolff ring contraction and a stereoselective HAT reduction, our synthetic approach has enabled the access to (−)-retigeranic
描述了 (−)-retigeranic acid A 的不对称全合成,它依赖于关键的还原骨架重排级联,用于不同角三喹啉亚基的可控组装。结合分子内 Michael/aldol 环化、ODI-[5 + 2] 环加成/频哪醇重排级联、Wolff 环收缩和立体选择性 HAT 还原,我们的合成方法能够在简洁实用的方式。

of (−)-retigeranic acid A has been realized. The key features of the current synthesis include (1) a Pt-catalyzed Conia-ene 5-exo-dig cyclization of enolyne to establish the key quaternary stereochemical center of C-10 (D/E ring), (2) an intramolecular diastereoselective Prins cyclization to construct the trans-hydrindane backbone (A/B ring), and (3) a late-stage intramolecular Fe-mediated hydrogen
