    • EPR spin trapping experiments using 5,5-dimethylpyrroline N-oxide were also unfruitful. Multiple trapping products were observed. Furthermore, the superoxide adduct is unstable under the photolysis conditions.

    • It was independently demonstrated that the deoxyribonolactone (1) does not undergo deuterium or oxygen exchange under the reaction conditions.

    • The yield of 6 was >90% of the amount of 10 consumed during photolysis. Consumption of 10 was established by reversed-phase HPLC. The yield of 6 was determined by GC/MS analysis following persilylation. Both compounds were quantitated using internal standards.

    • (b) During the photolysis (2 h), ∼25% of a solution of 10 (50 μM) is converted in the RPR-100 photoreactor (equipped with one lamp). On the basis of this level of conversion, we estimate that the steady-state concentration of 4 during photolysis is at the nanomolar level. Consequently, the rate of reaction of two molecules of 4 (using the rate constant in ref 29a) is significantly slower than trapping of 4 by thiol.
