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.It acts as an activator for chiral iridium N, P ligand complexes, which can be utilized in the hydrogenation of α, β-unsaturated nitriles. The influence of varying concentration of N,N-diisopropylethylamine on the synthesis of olvanil in the presence of lipase catalyst has been investigated.
Application
N,N-Diisopropylethylamine may be used in the synthesis of mannosylated ovalbumin peptides.
TBDPS protection of Alcohols using tert-Butylchlorodiphenylsilane.
BOM protection of Alcohols using Benzyloxymethyl Chloride.
