“…Amine compounds are essential and valuable building blocks in the chemical industry and life sciences due to their nucleophilic characteristics and extensive applications in the industrial manufacturing of pharmaceuticals, agrochemicals, polymers, food additives, surfactants, and so forth. − Nowadays, over 80% of the top 200 prescription drugs and all the top 10 agrochemicals contain nitrogen in their molecules. , A variety of traditional industrial amine synthesis methods have been developed, including the alkylation of ammonia; the amination of alkyl halides; the hydrogenation of amides, nitriles, and nitro compounds; the amination of alcohols; and the reductive amination of carbonyl compounds. − In recent years, the reductive amination of carbonyl compounds has been an interesting route to synthesize amines because of its operational ease, mild reaction conditions, inexpensive and widely available substrates, and, theoretically, water as the sole byproduct. ,− In the pharmaceutical industry, at least a quarter of the C–N bonds are formed by reductive amination owing to its synthetic merits . Currently, in the context of the increasing scarcity of fossil resources (i.e., coal, oil, and natural gas), the utilization of abundant biomass-derived aldehydes and ketones through reductive amination has been recognized as an outstanding opportunity for the sustainable production of amines in the chemical industry. ,,,− …”
