A novel and efficient method for the preparation of secondaryamines by reductive amination of carbonyl compounds with primary amines has been developed. The reduction, effected with metallic magnesium in methanol, utilizing triethylamine–acetic acid as a buffer, gave pure secondaryamines, mostly in good yields (65–80%). No formation of tertiary amines or alcohols was observed. Use of ammonium acetate

The present invention relates to methods of treatment of a disease or pathology of the central nervous system, an eating disorder, or substance use disorder, drug dependence/abuse and withdrawal therefrom comprising administering at least one N-phenylalkyl amphetamine derivative and pharmaceutical compositions comprising at least one N-phenylalkyl amphetamine derivative to an individual in need thereof.
Reductive amination under hydrogen pressure is a valuable process in organic chemistry to access amine derivatives from aldehydes or ketones. Knölker’s complex has been shown to be an efficient iron catalyst in this reaction. To determine the influence of the substituents on the cyclopentadienone ancillary ligand, a series of modified Knölker’s complexes was synthesised and fully characterised. These

NaH2PO2 was found to promote reductive amination. Being nontoxic, stable, environmentally benign, and available in bulk amounts, this reducing agent showed a powerful potential to compete with classical reductants applied in the target process. An E factor of 1 was achieved for the substrate scope. Different carbonyl compounds reacted with amines under the developed conditions. The reaction demonstrated
