摘要
5-(Phenylthiomethyl)-2'-deoxyuridine was successfully incorporated into DNA oligomers by automated DNA synthesis using phosphoramidite chemistry. UV exposure of the latter thionucleoside containing oligonucleotides under anaerobic and aerobic conditions gives rise to specific base lesions. The photoproducts have been isolated and further characterized on the basis of NMR and mass spectrometric analyses.
