However, its instability has prevented its in vitro study, so far. With a view to prepare oligodeoxynucleotides containing the CC cyclobutane lesion, we have synthesized in good yield a ditetrazolouracil cyclobutane dinucleotide photoproduct as a stable precursor of this photoproduct. Our approach also overcomes the low photochemical reactivity of the cytosine-cytosine deoxydinucleoside monophosphate.
