The reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation.
WebA general and versatile method for C–C cross-coupling synthesis of conjugated enynes in one-pot sequence starting from readily available carbonyl compounds was developed by Lyapkalo and Vogel. 108 Although routinely, the coupling protocols consist of two steps that include O-sulfonylation of the starting carbonyl compounds, followed by Pd-catalyzed … Web4.28.2 Chemistry of Protein Glycation.
