developed for regioselective synthesis of highly substituted α-naphthols, binaphthols, and anthracenol through silver(I) catalyzed C(sp3)–H/C(sp)–H, C(sp2)–H/C(sp)–H functionalization of β-ketoesters and alkynes, respectively, in a single step using water as a solvent. This protocol exhibited broad substrate scope and paved the way for synthesis of anticancer arylnaphthalene lignan natural products such as
通过银(I)催化的C(sp 3 )–H/C(sp)–H、C(sp 2 )–H/C区域选择性合成高度取代的α-萘酚、联萘酚和蒽酚的新路线已被开发β-酮酯和炔烃的 (sp)–H 官能化,分别在一步中使用水作为溶剂。该方案展示了广泛的底物范围,为合成抗癌芳基萘木脂素天然产物(如diphyllin、taiwanin E和justicidin A)铺平了道路,具有优异的选择性。
