The catechol metabolites of estradiol, 2- and 4-hydroxyestradiol (2-OHE(2) and 4-OHE(2), respectively) are potent signaling molecules and are hypothesized to be central to estrogen-linked carcinogenesis. Methylation by catechol-O-methyltransferase (COMT) is the principal means of catechol estrogen (CE) deactivation in the liver and other tissues.

Catechol estrogen methylene ethers
Steroids, 1974Abstract We have prepared 2-hydroxyestrone 2,3-methylene ether and 2-hydroxy-estradiol 2,3-methylene ether; these compounds were not found as urinary metabolites of radioactive estrone, estradiol or 2-methoxyestrone in humans.

Catechol Monoglyceryl Ether Carbamates
Journal of Pharmaceutical Sciences, 1963Abstract A series of carbamates and N-methylcarbamates derived from 3-(o-hydroxyphen-oxy)-1,2-propanediol was prepared and screened for muscle relaxant activity. An ester interchange between the above diol and diethyl carbonate failed to give 4-(e-hydroxyphenoxymethyl)-1,3-dioxolone-2; 2-hydroxymethyl-1,4-benzodioxane was obtained instead.

Nucleophilic Deoxyfluorination of Catechols
Organic Letters, 2011Nucleophilic 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 analogues.

Summary When catechol, the simplest o-dihydroxy aromatic compound, is oxidized in the presence of potassium alum, there results a solution which stains very similarly to an alum hematoxylin.
