일반 설명
4-(Dimethylamino)pyridine (DMAP) is a highly versatile nucleophilic catalyst for acylation reactions and esterifications. It is also employed in various organic transformations like Baylis-Hillman reaction, Dakin-West reaction, protection of amines, C-acylations, silylations, applications in natural products chemistry, and many others.
애플리케이션
4-(Dimethylamino)pyridine can be used as a catalyst:
- To synthesize 3,5-disubstituted 2,6-dicyanoaniline by reacting malononitrile, aldehydes, and β-nitroolefins.
- For the acylation of alcohols with acid anhydrides under auxiliary base- and solvent-free conditions to synthesize corresponding esters.
- In Baylis-Hillman reaction to form carbon-carbon bond by the coupling of an activated alkene with an aldehyde or ketone.
A highly efficient catalyst for acylation reactions
