Importance and Green Synthesis of Amines: A Review

Abstract: Amines are “derivatives of ammonia” and important key intermediates for applications in the industrial, pharmaceutical, electronics, etc. They have been used to synthesize industrially important azo dyes, which are used to color various materials. Moreover, amine functionality is present in several important biological molecules. Biogenic amines are found in living organisms and play essential physiological functions in the body. They are prepared from the amination and transamination reaction of carbonyl compounds such as aldehydes and ketones and the decarboxylation reaction of amino acids. Thus, the various applications and requirements of essential amine scaffolds paid attention to researchers to develop novel synthetic protocols to synthesize these compounds. In organic chemistry, various methods synthesize amines; however, green synthetic methods have recently become a trend. By writing this review, our main focus was to provide a brief on the importance of some biogenic amines and the synthesis of both amines via green synthetic methods.
