2'-OMe-ibu-G Phosphoramidite Usage And Synthesis

Chemical Properties

The IUPAC Name is N-[9-[(2R,3R,4R,5R)-5-[[bis(4-methoxyphenyl)-phenylmethoxy]methyl]-4-[2-cyanoethoxy-[di(propan-2-yl)amino]phosphanyl]oxy-3-methoxyoxolan-2-yl]-6-oxo-1H-purin-2-yl]-2-methylpropanamide

Uses

2''-OMe-ibu-G Phosphoramidite (CAS# 150780-67-9) is used in the synthesis of native-like crosslinked duplex RNA via interstrand crosslinking reaction between vinylpurine on one strand and target cytosine or uracil on the opposite strand.

Definition

2'-OMe-ibu-G Phosphoramidite is a chemically unstable and heat-sensitive nucleoside phosphoramidite that serves as a foundational element in oligonucleotide synthesis. 2'-OMe-RNA CE (β-cyanoethyl) Phosphoramidites are designed to produce synthetic oligonucleotides containing nuclease resistant 2'-O-methyl ribonucleotide linkages. Deprotection, isolation and handling of 2'-O-methyl oligonucleotides are identical to the procedures for oligodeoxynucleotides.
