Synthesis and Incorporation of a Simple Acyclic Furan Containing Phosphoramidite

Abstract

A novel furan containing phosphoramidite was synthesized and incorporated into model oligonucleotides. This glycol nucleic acid based building block contains a furan unit substituting the natural base, and can be used for post synthetic oligonucleotide modifications by orthogonal chemistries such as Schiff base formation after in situ oxidation or Diels-Alder cycloadditions.
