2'-O-Propargyl-G (iBu) CE Phosphoramidite is a click-handle RNA building block: 5'-O-(4,4'-dimethoxytrityl)-N2-isobutyryl-2'-O-(prop-2-yn-1-yl)guanosine 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. It is identified by CAS 171486-61-6, molecular formula C47H56N7O9P, molecular weight 894.0, PubChem CID 137126455, and InChIKey AGWGPRXHCUPJJO-VCGWOZLGSA-N.
The 2'-O-propargyl group is a permanent 2'-O-ether that carries a terminal alkyne (C≡CH) — it is not a protecting group. That terminal alkyne is a "click" handle: oligonucleotides bearing a terminal alkyne can be labeled after synthesis by the copper-catalyzed azide-alkyne cycloaddition (CuAAC) with azide-bearing reporters. The monomer couples through a standard 3'-phosphoramidite (3'→5' linkages), the 5'-DMT is removed each cycle, and the N2-isobutyryl base group is removed at final deprotection.

应用背景
- Internal click handle: the 2'-O-propargyl ether places a terminal alkyne at the 2'-position for post-synthetic conjugation.
- CuAAC labeling: the terminal alkyne reacts with azide-bearing reporters (dyes, biotin, other tags) by the copper-catalyzed azide-alkyne cycloaddition (click chemistry).
- 3'→5' coupling monomer: the 3'-phosphoramidite couples to form 3'→5' linkages; the 5'-DMT is removed each cycle and the N2-isobutyryl base-protecting group is removed during final deprotection.

常见问题
What does the 2'-O-propargyl group provide?
It is a permanent 2'-O-ether that carries a terminal alkyne. The alkyne is a 'click' handle: after synthesis, the oligonucleotide can be conjugated to azide-bearing reporters (dyes, biotin, etc.) by the copper-catalyzed azide-alkyne cycloaddition (CuAAC).
Why is the guanine isobutyryl-protected?
The N2-isobutyryl group masks the guanine exocyclic amine during synthesis and is removed at final deprotection. The 5'-DMT is removed each coupling cycle, while the 2'-O-propargyl ether stays on the finished oligonucleotide as the click handle.
