title: Synthesis of labelled PNA oligomers by a post-synthetic modification approach.
abstract: The preparation of t-butoxycarbonyl (Boc)-protected O(4)-(o-nitrophenyl) thymine peptide nucleic acid (PNA) monomer is described. This PNA monomer was incorporated into PNA oligomer sequences. The post-synthetic modification of the oligomers to yield fluorescently-labelled PNA oligomers was studied before and after the removal of the protecting groups. In both cases, the desired fluorescently-labelled PNA oligomer was obtained in good yields.
