Naphthol and lens.

Indian journal of medical sciences, 1992
Alpha and beta naphthols, the metabolites of naphthalene, a cataractogenic agent, was tested for it's effect on sheep lens proteases and their inhibitors. It reduced protease activities, not that of inhibitor activities of lens proteins. It also increased the efflux of free amino acid from lenses which was retarded by a high concentration of tissue ...

The Effects of Substituents on the pKα, Values of "meta"-Substituted 1- and 2-Naphthols

, 1963
pKa values (H2O at 25 C) have been measured for 3-substituted 1-naphthols and 4-substituted 2-naphthols and the results show that the behaviour of these compounds is similar to that of the equivalent naphthylamines.

Regioselective Transition Metal-Free Catalytic Ring Opening of 2H‑Azirines by Phenols and Naphthols; One-Pot Access to Benzo- and Naphthofurans

Benzofuran and naphthofuran derivatives are synthesized from readily available phenols and naphthols. Regioselective ring openings of 2H-azirine followed by in situ aromatization using a catalytic amount of Brønsted acid have established the novelty of ...

Hydrogenolysis of Aromatic Oxygenates Over Pt/WO3–ZrO2 in a Water/Decane Biphasic System

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Combining a water‐tolerant Pt/WO3–ZrO2 catalyst with a water/decane biphasic system enables efficient hydrogenolysis of lignin‐derived aromatic oxygenates under mild conditions. Spatial separation of the catalyst and arene products suppresses over‐hydrogenation, providing high aromatic selectivity at only 90 °C and 0.1 atm H2.

Enantioselective Organocatalytic Sulfenylation of β‑Naphthols

, 2018
An enantioselective sulfenylation of β-naphthols has been developed for the first time using a newly synthesized cinchona-derived thiourea as the catalyst and N-(arylthio) succinimide (or phthalimide) as an electrophilic sulfur source.

Insights into the Enantioselective Au(I)‐Catalyzed Reactions between 2‐Alkynyl Ketones and Naphthols using the TCDC Approach

International audienceThe CPAPhosAuCl bifunctional complexes catalyse the enantioselective tandem cycloisomerization‐nucleophilic addition reactions between 2‐alkynylenones and naphthols, where naphthols behave mainly as O‐nucleophiles.
