Abstract
A novel route has been developed
for regioselective synthesis of
highly substituted α-naphthols, binaphthols, and anthracenol
through silver(I) catalyzed C(sp<sup>3</sup>)–H/C(sp)–H,
C(sp<sup>2</sup>)–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 diphyllin, taiwanin E, and justicidin A with excellent selectivity
