Descripción

Application

2-Cyanoethyl N,N-diisopropylchlorophosphoramidite was employed:

• for selective monophosphorylation of carbohydrates and nucleosides
• for conversion of protected ribonucleosides to phosphoramidites
• as phosphitylating reagent for 3′-hydroxyl groups in the synthesis of oligodeoxyribonucleotides
• in a scalable, solution-phase oligonucleotide synthesis employing phosphoramidite chemistry and DMT-, iBu- and Bz-protected monomers. Intermediates were isolated by extraction without further purification
