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