Radical scavenging effects of 1-naphthol, 2-naphthol, and their sulfate-conjugates

The Journal of Toxicological Sciences, 2018
1-Naphthol (1-Nap) and 2-naphthol (2-Nap) are phenolic isomers that may be subjected to sulfate conjugation in vivo. Phase-II sulfate conjugation of phenolic compounds is generally thought to result in their inactivation. This study aimed to investigate the antioxidative effects of 1-NapS and 2-NapS, in comparison with their unsulfated counterparts ...

Catalytic Regiodivergent Dearomatization Reaction of Nitrosocarbonyl Intermediates with β‑Naphthols

, 2019
The divergent reactivity of nitrosocarbonyls in oxidative dearomatization of β-naphthols is reported. In the presence of quinidine catalyst, their reactions with α-unsubstituted β-naphthols proceeded through the N-center to furnish α-imino-β ...

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, EarlyView.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

One-Pot Synthesis of 2′-Aminobenzothiazolo-Arylmethyl-2-Naphthols Catalyzed by NBS under Solvent-Free Conditions

The Scientific World Journal, 2013
To develop a new facile protocol for the synthesis of 2′-aminobenzothiazolo-arylmethyl-2-naphthol derivatives, N-bromosuccinimide (NBS) was used as an efficient catalyst for the one-pot synthesis of 2′-aminobenzothiazolo-arylmethyl-2-naphthols in ...

Coordination Chemistry of Boron Subphthalocyanine With BINOL Derivatives: Unexpected Oxidation to Oxa[4]Helicene and Properties of the Resulting Axially Coordinated Complexes Containing Oxa[4]Helicene and/or BINOL Derivatives

Chemistry – A European Journal, EarlyView.
Treatment of BINOL with a boron subphthalocyanine derivative resulted in the formation of a complex coordinated to an oxa[4]helicene derivative, which is generated via a ring‐closure reaction of BINOL. In contrast, treatment of the monomethyl ether of 1,1′‐bi‐2‐naphthol (BINOL) afforded the expected axially coordinated complex.
