3'-NH-Trt-2',3'-ddG (iBu) 5'-CE Phosphoramidite is a building block for N3'→P5' phosphoramidate oligonucleotide chemistry: a 3'-tritylamino-2',3'-dideoxyguanosine with N2-isobutyryl protection and a 5'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. Its PubChem-backed identity includes CAS 195375-66-7, molecular formula C42H51N8O5P, molecular weight 778.9, PubChem CID 135506969, and InChIKey USNNKXWWDUBLFP-MICLYWDSSA-N.
Unlike a standard amidite, the 3'-position carries a trityl-protected primary amine in place of the 3'-hydroxyl, and the phosphoramidite is on the 5'-position as a reverse amidite. During synthesis, the incoming monomer's 5'-phosphoramidite couples to the 3'-amino group of the growing chain, forming a P-N phosphoramidate bond (an N3'→P5' linkage) instead of the natural phosphodiester. Cited phosphoramidate literature reports nuclease-hydrolysis, duplex-stability, and RNA-like C3'-endo conformation context for this backbone class. N2-isobutyryl protects the guanine amine and is removed during final deprotection.

用途情報
- N3'→P5' phosphoramidate linkage: the 3'-amino group couples to the next residue's 5'-phosphorus, forming a P-N phosphoramidate bond in place of a phosphodiester.
- Reverse (5'-)amidite: the phosphoramidite is on the 5'-position and the 3'-amine is trityl-protected, so chain assembly runs in the 5'→3' sense for this chemistry.
- Backbone literature context: cited N3'→P5' phosphoramidate literature reports nuclease-hydrolysis, duplex-stability, and RNA-like C3'-endo conformation context; N2-isobutyryl protects the guanine amine.

よくある質問
What is an N3'→P5' phosphoramidate?
It is a modified backbone linkage in which the phosphorus joins the 3'-nitrogen of one nucleoside to the 5'-oxygen of the next (a P-N bond), instead of the natural 3'-oxygen phosphodiester. It is built from 3'-amino-3'-deoxy nucleosides like this one.
