Abstract

The H-phosphonate of a derivative of thioctic acid (TA) was synthesized and used to introduce a disulfide moiety at the 5'-end of oligonucleotides. This method overcomes the difficulties experienced with the phosphoramidite approach when employing a cyclic disulfide in the starting alcohol. The disulfide-modified oligonucleotides are subsequently used in metallic nanoparticle (Au and Ag) and surface functionalisation for sensitive, sequence specific analytical detection strategies.
