2'-Deoxyuridine CE Phosphoramidite is the 2'-deoxyuridine building block for DNA synthesis: 5'-O-(4,4'-dimethoxytrityl)-2'-deoxyuridine bearing a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65007 is identified by CAS 109389-30-2, molecular formula C39H47N4O8P, molecular weight 730.8, PubChem CID 11061591, and InChIKey ZGJUDTLSWZPIDW-MVFNBKNKSA-N.

Nucleoside phosphoramidites are the coupling monomers used in automated solid-phase oligonucleotide synthesis: the 3'-phosphoramidite is the reactive group that couples to the growing chain, and the acid-labile 5'-DMT is removed at the start of each cycle. Because uracil has no exocyclic amine, no base protecting group is required.

응용 맥락

  • DNA coupling monomer: the 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite is the reactive group that couples to the growing oligonucleotide chain in automated solid-phase synthesis.
  • 5'-DMT 5'-OH protection: the acid-labile 4,4'-dimethoxytrityl group is removed at the start of each chain-elongation cycle.
  • No base protection needed: uracil has no exocyclic amine, so this monomer requires no base protecting group.

자주 묻는 질문

Why does the 2'-deoxyuridine phosphoramidite have no base protecting group?

Uracil has no reactive exocyclic amine, so it needs no base protection. The monomer carries only the acid-labile 5'-O-DMT group (removed each cycle) and the 3'-phosphoramidite coupling group.

How does it relate to 5'-O-DMT-2'-deoxyuridine?

It is the phosphoramidite of that nucleoside: the 3'-hydroxyl has been converted to a 2-cyanoethyl N,N-diisopropyl phosphoramidite. The 5'-O-DMT-2'-deoxyuridine precursor is cataloged separately.
