Heterogeneously Catalyzed Carboxylic Acid Hydrogenation to Alcohols [PDF]
, 2022 This critical review discusses the synthesis of alcohols via hydrogenation of carboxylic acids promoted by heterogeneous metal catalysis. The introductory chapter rationalizes the comparative reactivity of carboxylic acid derivatives, which is proceeded ...

Valorization of Lignin by Partial Wet Oxidation Using Sustainable Heteropoly Acid Catalysts
Molecules, 2017 The production of carboxylic acids by partial wet oxidation of alkali lignin at elevated temperatures and pressures was studied experimentally. Two different heteropoly acids, phosphotungstic acid (H3PW12O40) and phosphomolybdic acid (H3PMo12O40), were ...

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols
FEBS Open Bio, EarlyView.Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Indole-3-carboxylic acid [PDF]
, 2003 The crystal structure of indole-3-carboxylic acid, C9H7NO2, shows the presence of centrosymmetric hydrogen-bonded cyclic carboxylic acid dimers [OO = 2.649 (2) ŝ. These dimers are linked into a sheet structure through peripheral intermolecular hydrogen

Crystal structure of zymonic acid and a redetermination of its precursor, pyruvic acid
Acta Crystallographica Section E: Crystallographic Communications, 2019 The structure of zymonic acid (systematic name: 4-hydroxy-2-methyl-5-oxo-2,5-dihydrofuran-2-carboxylic acid), C6H6O5, which had previously eluded crystallographic determination, is presented here for the first time.

FEBS Open Bio, EarlyView.The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.

Modeling the hydrolysis of perfluorinated compounds containing carboxylic and phosphoric acid ester functions, alkyl iodides, and sulfonamide groups [PDF]
, 2009 Temperature dependent rate constants were estimated for the acid- and base-catalyzed and neutral hydrolysis reactions of perfluorinated telomer acrylates (FTAcrs) and phosphate esters (FTPEs), and the SN1 and SN2 hydrolysis reactions of fluorotelomer ...

New Synthesis of 7-azabicyclo[2.2.1]heptane-1-carboxylic acid [PDF]
, 2001 This report describes a new synthetic route to 7-azabicyclo[2.2.1]heptane-1-carboxylic acid (Ahc), a constrained proline analogue, in which the key step is the Diels-Alder reaction using methyl 2-benzamidoacrylate as dienophile.

Structure Property Relationships of Carboxylic Acid Isosteres [PDF]
, 2016 The replacement of a carboxylic acid with a surrogate structure, or (bio)-isostere, is a classical strategy in medicinal chemistry. The general underlying principle is that by maintaining the features of the carboxylic acid critical for biological ...
