Oxidation of aromatic aldehydes by Serratia marcescens.
Cell suspensions of Serratia marcescens catalyzed the oxidation of aromatic aldehydes into the corresponding acids in high yield under mild conditions.
متن کاملNickel-Catalyzed Decarbonylation of Aromatic Aldehydes.
We report here the first systematic study of nickel-catalyzed decarbonylation of aromatic aldehydes under relatively mild conditions. Aldehydes with electron donating groups at para and ortho positions are generally successful with our method. For aldehydes with electron-withdrawing groups, significantly higher yields were achieved for ortho-substituted substrates than para ones, probably due t...
متن کاملBiotransformation of Aromatic Aldehydes by Cell Cultures of Peganum harmala L. and Silybum marianum (L.) Gaertn.
Many aldehydes are important components of natural flavours. They are used in food, cosmetic, and biomedical industries in large amounts. Plant cells or microorganisms carry out their production by biotransformation, which is one of the biotechnological methods that allow them to be defined as 'natural'. Cell cultures of Silybum marianum and Peganum harmala have been studied with a view to in...

متن کاملReaction of benzoylpyruvate with a mixture of aromatic aldehydes and 5-amino-1,3,4-thiadizole-2-thiol
Reactions of benzoylpyruvate with a mixture of aromatic aldehydes and 5-amino-1,3,4-thiadizole-2-thiol in a 1:1:1 molar ratio, afforded 5-(5-aryl-4-benzoyl-3-hydroxy-2-oxo-2,5-dihydro-1H-pyrrol-1-yl)-1,3,4-thiadizole-2-thiols (3a-c). The structure of the resulted products was confirmed by determination of the melting point and spectrophotometric techniques such as IR and 1H-NMR spectroscopy.
