and 17, useful intermediates toward the angucyclines, either benz[a]anthraquinone-type or naphthacenequinone-type, has been developed based on (1) the O→C-glycoside rearrangement and (2) the regioselective cycloaddition of α-alkoxybenzyne and α-oxyfuran. The first total synthesis of galtamycinone (2), the common aglycon of naphthacenequinone-type angucyclines, has been achieved by utilizing 17 as the
两步访问Ç α-糖基juglones,16和17,朝着angucyclines有用的中间体,或者苯并[一个]蒽醌型或萘并萘醌型,已经基于开发(1)ø → Ç糖苷重排和(2)α-烷氧基苯并and和α-氧呋喃的区域选择性环加成。通过使用17作为关键中间体,首次实现了萘并醌型蒽环素的常见糖苷配基半乳糖苷(2)的首次全合成。
