atom‐economic, enantio‐, and diastereoselective synthetic route to trisubstituted γ‐butyrolactones based on a Wagner–Meerwein‐type dyotropic rearrangement of cis‐β‐lactones is described (see scheme). This methodology was applied in efficient and protecting‐group‐free formal syntheses and total syntheses of various xanthanolide natural products.
让我们交换一下:描述了一种基于Wagner-Meerwein型顺式-β-内酯重排的可扩展,原子经济,对映和非对映选择性的合成三取代γ-丁内酯的方法(参见方案)。该方法学被用于各种黄原醇天然产物的高效且无保护基团的形式合成和总合成中。
