Catalytic Amination of Phenols with Amines
Journal of the American Chemical Society, 2022Given the wide prevalence and ready availability of both phenols and amines, aniline synthesis through direct coupling between these starting materials would be extremely attractive. Herein, we describe a rhodium-catalyzed amination of phenols, which provides concise access to diverse anilines, with water as the sole byproduct.

This chapter provides a brief description of the use of amines and amine-borane complexes as reducing agents for the synthesis of metallic nanoparticles. The use of alkyl, aryl amines, hydrazine, amine-borane complexes and, finally, polymeric amines is discussed in relation to their ability to reduce different classes of metallic ions (noble, magnetic,

C R C Critical Reviews in Food Science and Nutrition, 1978
Amines represent a class of compounds which historically have been associated with fishery products and cheese; however, this review clearly demonstrates that their occurrence is widespread in our food supply. In addition, their formation pathways, methods of isolation and identification, and sensory properties are discussed.

Development of an Amine Dehydrogenase for Synthesis of Chiral Amines
Angewandte Chemie - International Edition, 2012A leucine dehydrogenase has been successfully altered through several rounds of protein engineering to an enantioselective amine dehydrogenase. Instead of the wild-type α-keto acid, the new amine dehydrogenase now accepts the analogous ketone, methyl isobutyl ketone (MIBK), which corresponds to exchange of the carboxy group by a methyl group to produce

Biogenic amines (BAs) are among the most common nitrogenous compounds, widely present in plants, microbes and animal cells. Although BAs play an important role in regulating a number of important biological functions in the human body, overuse of certain bases can cause serious toxicological effects.

Publisher Summary This chapter discusses amines in schizophrenia. Effects of phenothiazines upon brain catecholamines would be relevant to schizophrenia only if the phenothiazine drugs exerted a selective antischizophrenic action, so that their primary site of action might be assumed to play a prominent role in brain dysfunction in schizophrenia ...

Mono/Dual Amination of Phenols with Amines in Water
Organic Letters, 2020We herein describe a practical direct amination of phenols through a palladium-catalyzed hydrogen-transfer-mediated activation method to synthesize the secondary and tertiary amines. In this conversion, environmentally friendly water and inexpensive ammonium formate were used as solvent and reductant, respectively.
