5'-Dimethoxytrityl-N3-(2-cyanoethyl)-2'-deoxyThymidine,3'-[(2-cyanoethyl)-(N,N-diisopropyl)]-phosphoramidite
Description
The most common side reaction during deprotection of oligonucleotides on a large scale is the alkylation of dT residues by acrylonitrile, formed by ß-elimination of the cyanoethyl phosphate protecting groups, to generate N3-cyanoethyl-dT.
