Design and synthesis of the novel cross-linking agent

Previously, we have developed a highly efficient and selective cross-linking reaction to the cytosine base at the target site of DNA using the oligodeoxynucleotide (ODN) containing 2-amino-6-vinylpurine derivative (1). Based on these results, we have designed the novel cross-linking agents, which are pyrimidine derivatives having two hydrogen bond sites and vinyl group as a reactive moiety. In this paper, we wish to report the results to investigate on the synthesis of the pyrimidine derivatives having potential as novel cross-linking agents.
