2-Cyanoethyl N,N,N',N'-tetraisopropylphosphorodiamidite Chemical Properties,Usage,Production

Description

2-Cyanoethyl N,N,N',N'-tetraisopropylphosphorodiamidite is a colorless viscous liquid, which is soluble in most organic solvents. It is a widely used phosphitylating reagent for the preparation of various phosphorylated biomolecules, such as nucleoside carbohydrate conjugates, phospholipids and glycopeptides. In particular, this reagent is highly effective for automated solid-phase DNA/RNA oligonucleotide synthesis. It has shown great utility in the coupling of nucleobases or carbohydrates via their phosphotriesters in the presence of activators such as 1H-tetrazole, in moderate yields under mild conditions.This compound is cheaper and more stable than 2-cyanoethyl N,N-diisopropylchlorophosphorodiamidite (the other commonly used phosphinylating reagent)[1].

Chemical Properties

Clear to Cloudy Colourless Liquid

Uses

Reagent for synthesizing phosphitylated nucleotides.1

Uses

2-Cyanoethyl N,N,N′,N′-tetraisopropylphosphordiamidite was used:

in preparation of prosphoramidite reagent, required for synthesis of 12-mer oligodeoxynucleotide
as phosphorylating agent in synthesis of 1,2-diacyl-sn-glycerophosphatidylserine
in situ preparation of deoxyribonucleoside phosphoramidites
in preparation of 2′-deoxy-2′-fluoro-3′-O-(β-cyanoethyl-N,N-diisopropylphosphoramidic)-5′-O-(4-methoxytrityl)-4′-thio-β-D-arabinouridine and 1-(3-O-(β-cyanoethyl-N,N-diisopropylphosphoramidic)-2-deoxy-2-fluoro-5-O-(4,4′-dimethoxytrityl)-4-thio-β-D-arabinofuranosyl)-thymine
as reagent for synthesizing phosphitylated nucleotides

Application

2-Cyanoethyl N,N,N',N'-tetraisopropylphosphorodiamidite is an important organic reagent widely used in the preparation of modified and unmodified nucleoside phosphoramidites. Nucleoside phosphoramidites are ideal reagents for polymer-supported synthesis of oligonucleotides. The diisopropylamino leaving group is readily cleaved upon contact with the azole catalyst, resulting in an efficient coupling reaction with the free hydroxyl group on the protected nucleoside.

Synthesis

3-((dichlorophosphaneyl)oxy)propanenitrile could synthesize 2-Cyanoethyl N, N, N', N'-tetraisopropylphosphorodiamidite with diisopropylamine. This method is inexpensive manner using a two-step, one-pot procedure and purified by vacuum distillation[2].
