Description

General description

N, N-Diisopropylethylamine is a hindered non-nucleophilic amine base used in alkylation, aldol-like reactions, eliminations, and selective generation of enolates. It is widely used as a proton scavenger in organic synthesis. Due to its less nucleophilic nature, it produces less byproducts.

Application

N, N-Diisopropylethylamine can be used as a base:

• In the palladium (0)-catalyzed alkoxy carbonylation of allyl phosphates and acetate.
• In the selective enolate formation along with boryl triflates.
• In the C–N coupling of aryl halides with nitroarenes in the presence of nickel catalyst.

N,N-Diisopropylethylamine may be used in the synthesis of mannosylated ovalbumin peptides.
