The article was written by Schmalzbauer, Matthias; Svejstrup, Thomas D.; Fricke, Florian; Brandt, Peter; Johansson, Magnus J.; Bergonzini, Giulia; Koenig, Burkhard. The article contains the following contents:
A redox-neutral CH carboxylation of arenes and styrenes using a photocatalytic approach was described for the synthesis of aryl/unsaturated-carboxylic acids RCOOH [R = 1-naphthyl, CH=CHPh, 5-cyano-2-thienyl, etc.]. Upon blue-light excitation, the anthrolate anion photocatalyst was able to reduce many aromatic compounds to their corresponding radical anions, which react with CO2 to afford carboxylic acids. High-throughput screening and computational anal. suggest that a correct balance between electron affinity and nucleophilicity of substrates was essential. This novel methodol. enabled the carboxylation of numerous aromatic compounds, including many that were not tolerated in classical carboxylation chem. Over 50 examples of CH functionalizations using CO2 or ketones illustrated a broad applicability. The experimental process involved the reaction of Pyrazolo[1,5-a]pyridine-7-carboxylic acid(cas: 474432-62-7Recommanded Product: 474432-62-7)
Pyrazolo[1,5-a]pyridine-7-carboxylic acid(cas: 474432-62-7) belongs to pyrazoles. Pyrazoles are commonly used scaffold molecules in drug discovery projects. The use of pyrazole derivatives is based on their analgesic, monoamine oxidase inhibitory, anti-inflammatory, antipyretic, neuroleptic, anticonvulsant, antiarrhythmic, sedative, muscle relaxant, antidiabetic and antibacterial activities.
