Descrição geral

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.

Aplicação

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

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
