Reductive amination is an important synthetic method in organic synthesis, in which carbonyl compounds and amines are mixed with reducing agents. A variety of reducing agents are known to effect reductive amination of aldehydes and ketones. These are hydrogen in the presence of metal catalyst, 1 sodium borohydride, 2 borane–pyridine, 3 borohydride exchange resin (BER), 4 zinc–acetic acid, 5 sodium borohydride–magnesium perchlorate, 6 zinc ...
