fluorine substitution that occurs and more than one fluorine atom may halogenate the aromatic ring. For iodine to substitute on an aromatic ring, the metal halides are not effective catalysts, but an oxidizer such as nitric acid will convert iodine to HIO3 and enable the iodization of benzene....

The “darkturquoise” gene module showed a strong correlation with the concentration of phenolic acids, such as Syringin (r = 1.0, P < 0.01), 3,4-Dihydroxybenzeneacetic acid (r = 0.99, P < 0.01), Sinapaldehyde-4-O-Glucoside (r = 0.99, P < 0.01), 2-O-...
(Supplementary Fig.5b), which is common in opioid analgesics64. For the functional groups, all datasets share top functional groups such as benzenes and amines, which are key components to facilitate interacting with drug targets, typically proteins with abundant amino acid residues, via forming ...

hydroxycarboxylic acids (ether carboxylic acids) and esters (benzene compounds6-Chloro-3,5-dimethoxyhomophthalic acid (I) was synthesized as a key intermediate for the synthesis of radicicol and isocoumarins of natural origin, via a sequence of reactions including cyclization of 3-(2-chloro-3,5...
The reaction from DHBQ to RhA involves pentahydroxybenzene (PHB, I) as an intermediate which is either readily further oxidized to RhA by excess ClO2 or slowly reconverted to DHBQ in the absence of ClO2. The RhA yield after 30 min reaction time had a maximum of 83% at a DHBQ/ClO2 ...
