Thiophosphorylated Resorcinol, Calix[4]resorcinols, and Other Hydroxyphenols [PDF]

open access: yesPhosphorus, Sulfur and Silicon and the Related Elements, 2011
Perdithiophosphonic acids are new types of tetracoordinated phosphorus thioacids bearing many dithiophosphoryl groups. Novel perdithiophosphonic acids were obtained by the reactions of 2,4-diaryl-1,3,2,4-dithiadiphosphetane-2,4- disulfides with hydroxyphenols such as resorcinol, 4,4'-iso- propylidenebisphenol, pyrogallol, and calix[4]resorcinols ...

Enantioselective Organocatalytic Synthesis of Bicyclic Resorcinols via an Intramolecular Friedel−Crafts‐Type 1,4‐Addition: Access to Cannabidiol Analogues [PDF]

open access: yesAdvanced Synthesis and Catalysis, 2021
The organocatalytic transformation of resorcinols is extremely rare. In this article, we report a highly enantioselective, organocatalytic intramolecular cyclization of these systems by a Friedel–Crafts-type 1,4-addition using a Jørgensen-Hayashi-like ...

Structure-Activity Relationships of Thiazolyl Resorcinols, Potent and Selective Inhibitors of Human Tyrosinase

open access: yesInternational Journal of Molecular Sciences, 2018
Tyrosinase inhibitors are of great clinical interest as agents for the treatment of hyperpigmentary disorders; however, most compounds described in the literature lack clinical efficiency due to insufficient inhibitory activity against human tyrosinase ...

Aqueous chlorination of resorcinol

Environmental Toxicology and Chemistry, 1989
Abstract An investigation of the aqueous chlorination (NaOCl) of resorcinol is reported. The following intermediates were detected in moderate to high yield at different pH values and varying percentages of chlorination: 2-chloro-, 4-chloro-, 2,4-dichloro-, 4,6-dichloro- and 2,4,6-trichlororesorcinol.
