Riboflavin Photocatalyzed Dearomative Spiro-Etherification of Naphthols

, 2023
The dearomative spiro-etherification of naphthols is achieved using catalytic amounts of riboflavin tetracetate (RFTA) as a photosensitizer and molecular oxygen as a terminal oxidizing agent under blue light (440 nm) irradiation in the presence of acid ...

Comparison between Electrooxidation of 1-Naphthol and 2-Naphthol in Different Non-Aqueous Solvents and Suppression of Layer Growth of Polymers

Surfaces
The two naphthol isomers were investigated in different organic solvents by taking cyclic voltammograms, and fouling took place on a platinum electrode surface, except for dimethyl sulfoxide and dimethyl formamide. Studies in allyl alcohol rarely used in

Arylglycine-derivative synthesis via oxidative sp3 C–H functionalization of α-amino esters

Beilstein Journal of Organic Chemistry, 2012
An efficient method for the synthesis of arylglycine derivatives is described. The oxidative coupling reactions of naphthols and phenols with α-amino esters proceeded smoothly in the presence of meta-chloroperoxybenzoic acid as an oxidant under ambient ...

Ligand-Controlled Nickel-Catalyzed Reactions of Benzocyclobutenones with Alkynyltrifluoroborates: Diverse Construction of Polysubstituted Naphthols

, 2023
Ligand-controlled nickel-catalyzed selective cleavage of the C1–C2 or C1–C8 bond of benzocyclobutenones (BCBs) is reported. The delicate selection of dpppe or PMe3 as the ligand led to predictably divergent synthesis of a wide range of 1-naphthols and 2 ...

Lewis acid promoted dearomatization of naphthols [PDF]

, 2020
Two-step dearomative functionalization of naphthols promoted by Lewis acids and copper(I) catalysis was developed. Initially, Lewis acid complexation inverted the electronic properties of the ring and established an equilibrium with the dearomatized ...
