  Synthesis and Application of a 5‘-Aldehyde Phosphoramidite for Covalent Attachment of DNA to Biomolecules

  摘要：

  We recently reported the use of covalently attached DNA as a structural constraint for rational control of macromolecular conformation. Reductive amination was employed to attach each strand of the duplex DNA constraint to RNA, utilizing an aldehyde tethered to the 5'-terminus of the DNA. Here we describe the synthesis of a thymidine phosphoramidite that has the 5'-tethered aldehyde masked as a 1,2-diol. We also describe optimized reductive amination conditions for linking 5'-aldehyde-DNA with 2'-amino-2'-deoxyRNA. These procedures should be generally applicable for attaching DNA to biomolecules.
