title: Preparation of 2'-hydrazino oligonucleotides and their reaction with aldehydes and 1,3-diketones.
abstract: Oligodeoxyribonucleotides that contain a hydrazino nucleoside, 2'-O-(2-hydrazinoethyl)uridine were prepared and shown to react with aldehydes or 1,3-diketones with the formation of hydrazones or pyrazoles, respectively. The method may be applicable for the preparation of oligonucleotide-peptide conjugates.
