A redox-neutral catechol synthesis
Nature Communications, 2017 Catechols are common structural motifs in bioactive molecules and synthetic building blocks. Here the authors report a method to convert phenol derivatives into catechols via an iridium-catalysed redox-neutral C–H hydroxylation, giving diversely ...

In vitro evaluation of the effect of C-4 substitution on methylation of 7,8-dihydroxycoumarin: metabolic profile and catalytic kinetics [PDF]
Royal Society Open Science, 2018 Daphnetin (7,8-dihydroxycoumarin (7,8-DHC)) and its C-4 derivatives have multiple pharmacological activities, but the poor metabolic stability of these catechols has severely restricted their application in the clinic.

International Journal of Electrochemical Science, 2007 Electrochemical oxidation of catechols (1a-e) has been studied in the presence of sulfite ion (3) as nucleophile in aqueous solution, using cyclic voltammetry and controlled-potential coulometry. The results indicate the participation of catechols (1a-e)

Nucleophilic Deoxyfluorination of Catechols
, 2016 Nucleophilic deoxyfluorinaiton of one of the two hydroxyl groups of catechols has been developed via the Umpolung concept. This method was successively applied to naturally occurring catechols, such as catechins and dopamine, to produce novel fluorinated

Enzymatic Allylation of Catechols
, 2015 Enzymatic allylation of catechols was realized via catechol O-methyltransferase (COMT) using an allylated S-adenosyl-L-methionine (allyl-SAM) analog, with relatively good chemo- and regioselectivities.
