General description
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.
Application
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

[Structure: see text] A powerful Ti-crossed Claisen condensation between ketene silyl acetals (KSAs) and acid chlorides was successfully performed to give alpha-monoalkylated esters and thermodynamically unfavorable (less accessible) alpha,alpha-dialkylated beta-keto esters in good yield (46 examples; 41-98% yield). A closely

A generic LC-MS/MS method was developed for the analysis of potentially genotoxic alkyl halides. A broad selection of alkyl halides were derivatized using 4-dimethylaminopyridine in acetonitrile. The reaction conditions for derivatization, i.e., solvent, reaction time, temperature and concentration of alkyl

An effective method for grafting L-lactide (LA) from unmodified cellulose by ring-opening polymerization (ROP) in homogeneous mild conditions is presented. By using 4-dimethylaminopyridine (DMAP) as an organic catalyst, cellulose-graft-poly(L-lactide) (cellulose-g-PLLA) copolymers with a molar substitution (MS(PLLA)) of PLLA in a
