Bacterial Decarboxylation of o-Phthalic Acids.
The decarboxylation of phthalic acids was studied with Bacillus sp. strain FO, a marine mixed culture ON-7, and Pseudomonas testosteroni. The mixed culture ON-7, when grown anaerobically on phthalate but incubated aerobically with chloramphenicol, quantitatively converted phthalic acid to benzoic acid. Substituted phthalic acids were also decarboxylated: 4,5-dihydroxyphthalic acid to protocatec...
متن کاملA mild deuterium exchange reaction of free carboxylic acids by photochemical decarboxylation.
Deuterium exchange of a carboxy group was achieved by photochemical decarboxylation of free carboxylic acids in the presence of thiol and a small amount of D(2)O, and a deuterated product with excellent deuterium content was obtained; this reaction is a practical means of synthesizing regioselective deuterium-labelled compounds under mild reaction conditions.

متن کاملSpectrophotometric Studies on the Decarboxylation of & Keto Acids
Reaction 1 is catalyzed by an enzyme widely distributed in animal tissues and present in some plants (1). Oxalacetic carboxylase, which catalyzes Reaction 2, has been found in bacteria (2), pigeon liver (3), and, to some extent, in other animal tissues as well as in plants (4). Mehler et al.’ have partially purified this enzyme from Microcowus lysocleikticus. Acetoacetic carboxylase (Reaction 3...
متن کاملHydroxylation and decarboxylation of hydroxybenzoic acids by Fe -chelates
4 2 containing FeSO and Na EDTA. EDTA could be replaced by citric acid. In this in vitro system 4hydroxybenzoic acid is hydroxylated to 3,4-dihydroxybenzoic acid (protocatechuic acid) and decarboxylated to hydroquinone. In an analogous reaction 2-hydroxybenzoic acid (salicylic acid) is hydroxylated to 2,3-dihydroxybenzoic acid and 2,5-dihydroxybenzoic acid (gentisic acid) and decarboxylated to ...
