Regioselective Enzymatic Carboxylation of Phenols and Hydroxystyrene Derivatives
The enzymatic carboxylation of phenol and styrene derivatives using (de)carboxylases in carbonate buffer proceeded in a highly regioselective fashion: Benzoic acid (de)carboxylases selectively formed o-hydroxybenzoic acid derivatives, phenolic acid (de)carboxylases selectively acted at the β-carbon atom of styrenes forming (E)-cinnamic acids.
متن کاملBase-mediated carboxylation of unprotected indole derivatives with carbon dioxide.
A simple and straightforward method for the preparation of indole-3-carboxylic acids was discovered through the direct carboxylation of indoles with atmospheric pressure of carbon dioxide (CO(2)) under basic conditions. The key for the reaction was found to be the use of a large excess of LiO(t)Bu as a base to suppress the undesired decarboxylation side reaction.
متن کاملInteraction of phenol derivatives with ion channels
Phenols began to play a prominent role very early in modern operative medicine in the 1860s when Lister introduced his ‘antisepsis’ approach. The treatment of open wounds by carbolic acid dramatically reduced morbidity and mortality of surgical patients for the first time [1]. This central place in operative medicine was lost when, in the early 20th Century, ‘asepsis’ replaced ‘antisepsis’. The...

متن کاملSynthesis and DPPH radical scavenging activity of prenylated phenol derivatives.
The synthesis of twenty six prenylated phenols derivatives is reported. These compounds were obtained under mild conditions via Electrophilic Aromatic Substitution (EAS) coupling reactions between phenol derivatives containing electron-donor subtituents and 3-methyl-2-buten-1-ol using BF(3)×OEt(2). Dialkylations were also produced with this method. The formation of a chroman ring by intramolecu...
