Application

N,N-Diisopropylethylamine may be used in the synthesis of mannosylated ovalbumin peptides.[1]
Proton scavenger used in peptide coupling,[2] enolboration,[3] Pd(0)-catalyzed alkoxycarbonylation of allyl phosphates and acetates,[4] and as a catalyst in vinyl sulfone synthesis.[5]

General description

N,N-Diisopropylethylamine, also known as Hünig′s base, is a sterically hindered amine. It is a non-nucleophilic base commonly employed for substitution reactions.[6] It acts as an activator for chiral iridium N, P ligand complexes, which can be utilized in the hydrogenation of α, β-unsaturated nitriles.[7] The influence of varying concentration of N,N-diisopropylethylamine on the synthesis of olvanil in the presence of lipase catalyst has been investigated.[8]
