The given reaction is believed to proceed through the intermediate shown. The complete and detailed mechanism that leads to the formation of the intermediate is to be drawn. Concept introduction: This reaction takes place under mildly acidic conditions, and this is evidenced by the presence of carboxylic acid groups. The aldehyde reacts with NH 3 in acidic conditions to form the imine according to the mechanism in equation 18-19, which is in equilibrium with a small amount of its protonated form. For the given reaction we have: The carbon nucleophile will be the enol. The ammonia deprotonates α-hydrogen of β-carboxylic acid to produce the enol that is nucleophilic at C.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
