说明

一般描述

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.

应用

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]
