We have previously demonstrated that 2-amino-6-vinylpurine is an efficient cross-linking agent with high selectivity towards cytidine. In this study, we applied this nucleobase analog to versatile conjugation of oligodeoxynucleotides with radio-, spin-, fluorescence- and peptide labels. The oligodeoxynucleotides incorporating 2-amino-6-vinylpurine nucleoside were reacted with amino- bearing nucleophies in an excess amount to give the corresponding conjugates in good yield.
