General description
NNDiisopropylethylamine also known as Hnigs base is a sterically hindered amine It is a nonnucleophilic base commonly employed for substitution reactionsIt acts as an activator for chiral iridium N P ligand complexes which can be utilized in the hydrogenation of unsaturated nitriles The influence of varying concentration of NNdiisopropylethylamine on the synthesis of olvanil in the presence of lipase catalyst has been investigated
Application
NNDiisopropylethylamine may be used in the synthesis of mannosylated ovalbumin peptides
