Base-promoted oxidative annulation of 2-naphthols and phenylglyoxal monohydrate via a metal-free, visible light-mediated reaction is reported for the synthesis of hydroxy-naphthofuranone, naphthofuranone, and naphthofuran with a broad substrate scope.
Triflic acid–thiol mediated reaction for the synthesis of two different products. Formation of the products depends upon the equivalents of thiol and triflic acid, with high selectivity under metal-free and additive-free reaction conditions.
This study reports the bacterial tyrosinase inhibiting potency of a series of novel 1,2,4-triazole-tethered β-hydroxy sulfide scaffolds 11(a–h), synthesized in good yields (69–90%).
We present a novel Zn-catalyzed aerobic oxidative ring-opening/[3 + 2] cyclization cascade of cyclopropanols with bromonaphthols, providing an eco-friendly and modular approach for synthesizing diverse naphthofuran derivatives.
Cu(II)-catalyzed divergent synthesis of naphthofurans and benzochromanes through [3 + 2 + 1] and [3 + 1 + 1] annulations is established.
