WebIn the Mannich reaction an amine (e.g., from a protein) is coupled in the presence of an aldehyde (usually formaldehyde, despite its toxic properties) to a suitable carbon atom in a wide range of organic compounds (Fig. 13).The carbon atom must possess an “active” hydrogen atom, loosely speaking, one with a degree of acidic character. Examples of … WebAnd this, essentially, is the Mannich reaction – it is a condensation of an aldehyde or ketone in form of an enol with an iminium ion producing β -aminoalkyl carbonyl compounds. The iminium ion is most often prepared from formaldehyde although it can be any nonenolizable, that is lacking alpha hydrogens, aldehyde, ketone, or oether C-H acid ... flannel shirt under coat

WebThe nitro-Mannich reaction (or aza-Henry reaction) is the nucleophilic addition of a nitroalkane (or the corresponding nitronate anion) to an imine, resulting in the formation of a beta-nitroamine. With the reaction involving the addition of an acidic carbon nucleophile to a carbon-heteroatom double bond, the nitro-Mannich reaction is related to some of the … flannel shirt two colors
