AbstractNatural phenethyl acetate (PEA), phenylacetic acid (PAA), ethyl phenylacetate (Et‐PA), and phenethyl phenylacetate (PE‐PA) are highly desirable aroma chemicals, but with limited availability and high price. Here, green, sustainable, and efficient bioproduction of these chemicals as natural products from renewable feedstocks was developed.

Dissociation constants of phenylacetic acid and three substituted phenylacetic acids
Journal of the Chemical Society B: Physical Organic, 1971The dissociation constants of four acids in aqueous solution have been determined at 25° by means of conductivity measurements. The pK values are: phenylacetic acid, 4·310; o-methylphenylacetic acid, 4·297; o-ethylphenylacetic acid, 4·317; o-fluorophenylacetic acid, 4·093.

Phenylacetic acid derivatives as hPPAR agonists
Bioorganic & Medicinal Chemistry Letters, 2003Beginning with the weakly active lead structure 1, a new series of hPPAR agonists was developed. In vivo glucose and triglyceride lowering activity was obtained by homologation and oxamination to 3, then conversion to substituted benzisoxazoles 4 and 5. Further manipulation afforded benzofurans 6 and 7. Compound 7 was of comparable potency as a glucose

Acid Strengths of the Phenylacetic Acids
Journal of The Electrochemical Society, 1953The ratio of dissociation constants Ksubstituted acid/Kacetic acid was determined in methanol and ethanol for mono‐, di‐, and triphenylacetic acid by the electrometric and colorimetric methods. In water, the insolubility of triphenylacetic made another procedure necessary with that acid, and the solubility method of Lowenherz was employed.

Shunting Phenylacetic Acid Catabolism for Tropone Biosynthesis
ACS Synthetic Biology, 2019Tropone is a seven-membered ring nonbenzenoid aromatic compound. It is the core structure of tropolonoids, which have various biological activities. In this study, a hybrid tropone biosynthetic pathway was designed by connecting phenylacetic acid (PAA) degradation with its biosynthesis and reconstituted in Escherichia coli.

Urinary phenylacetic acid excretion in depressive patients
Acta Psychiatrica Scandinavica, 1988ABSTRACTPhenylacetic acid (PAA), a metabolite of phenylethylamine, has been found in the urine of depressed patients at lower levels than in control subjects. It has been suggested that the determination of PAA in urine could be used as a biological marker of the depressive condition.

Tritium recoil labeling of phenylacetic acid
Journal of Labelled Compounds, 1975AbstractPhenylacetia acid has been labeled by means of the nuclear reaction 6Li(n,α)3H, both in mixture with Li2CO3 and as the lithium salt. The amount of Li2 CO3 was such as to keep the same weight ratio of lithium and phenylacetate ion as in the salt.It was observed that intimate mixtures of phenylacetic acid and lithium carbonate react slowly ...

Thermochemistry of phenylacetic and monochlorophenylacetic acids
The Journal of Chemical Thermodynamics, 2008Abstract The standard (p∘ = 0.1 MPa) molar enthalpies of formation in the crystalline state of phenylacetic acid and ortho-, meta- and para-chlorophenylacetic acids were derived from the standard molar energies of combustion in oxygen at T = 298.15 K, measured by combustion calorimetry. The Knudsen mass-loss effusion technique was used to measure the
