Decarboxylation - an overview | ScienceDirect Topics

Decarboxylation begins with an internal acid-base reaction, where the acid is the O H unit of the carboxylic acid, and the base is the oxygen of the carbonyl β to the acid moiety. Decarboxylation is possible because of the facile loss of a neutral leaving group carbon dioxide.

Transition metal-alyzed nonoxidative decarboxylation

The recent characterization of alpha-amino-beta-carboxymuconate-epsilon-semialdehyde decarboxylase (ACMSD) has revealed that this enzyme adopts a TIM-barrel (beta/alpha) (8) fold and employs a mononuclear transition metal center to decarboxylate the substrate in an oxidant-independent fashion. Thus, ACMSD represents a type of decarboxylation
