    • note
    • The HPLC profile (Supporting Information) of the irradiated sample showed a small peak appearing at a retention time characteristic for a deoxyribose derivative after the photocleavage of the pivaloyl group. An analysis of this signal by mass spectroscopy was not possible due to the low conversion of the reactant.

    • note
    • The same kind of EPR study was done on a double-stranded DNA in which a thymine nucleotide in the middle of the sequence was modified at the 4′ sugar site with a pivaloyl group. No appearance of the eight-line spectrum, also characteristic for a thymyl radical in DNA,[5d] could be detected. The spectrum (Supporting Information) shows a different pattern and is still under analysis.
