The first total synthesis of plumbazeylanone (1), which is a trimer of naphthoquinone, was carried out successfully utilizing the unsymmetrical methylene-bridged dimer with the naphthoquinone unit and the naphthol unit, 11b as a key intermediate in 11 steps. This synthesis features a regioselective nucleophilic 1, 2-addition reaction and dinone-phenol-type rearrangement.
利用具有
萘醌单元和
萘酚单元的非对称亚甲基桥接二聚体 11b 作为关键中间体,通过 11 个步骤成功地首次全合成了
萘醌三聚体 plumbazeylanone (1)。该合成具有亲核 1、2-加成反应和二酮-
苯酚型重排的区域选择性。
