L-rG (iBu) CE Phosphoramidite is a mirror-image RNA building block: 5'-O-(4,4'-dimethoxytrityl)-N2-isobutyryl-2'-O-(tert-butyldimethylsilyl)-L-guanosine 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. It is identified by CAS 679809-76-8, molecular formula C50H68N7O9PSi, molecular weight 970.2, PubChem CID 172909778, and InChIKey PGJKESPHANLWME-ZEXYNXKFSA-N.
It is the enantiomer of the natural D-guanosine amidite — built on L-ribose rather than D-ribose — so it has the same molecular formula and weight as its D-counterpart. The cited mirror-image oligonucleotide literature provides background for L-configured oligonucleotide chemistry and D/L strand-pairing orthogonality. The 2'-O-TBDMS group protects the 2'-hydroxyl, the 5'-DMT is removed each cycle, and the N2-isobutyryl base-protecting group is removed during final deprotection.

应用背景
- Mirror-image (L-ribose) monomer: provides the L-guanosine subunit identity for L-RNA synthesis.
- Mirror-image literature context: cited literature supports L-configured oligonucleotide chemistry and D/L strand-pairing orthogonality.
- RNA protection scheme: 2'-O-TBDMS protects the 2'-hydroxyl, the 5'-DMT is removed each cycle, and the N2-isobutyryl base-protecting group is removed during final deprotection.
