esters from cyclic anhydrides is reported using a modified Julia olefination. The reaction is highly stereoselective. The Smiles rearrangement can be performed in a one-pot process, giving a straightforward access to exo-enol lactones. Furthermore, the reaction was extended to semistabilized sulfones, and this methodology was applied to the synthesis of maculalactone B.
据报道,使用改进的朱莉娅烯化反应从环酐中制备外烯醇酯。该反应是高度立体选择性的。可以通过一锅法完成Smiles重排,直接获得exo- enol内酯。此外,该反应扩展到半稳定的砜,并且该方法学被用于合成黄酮内酯B。
