Nucleobases, Nucleosides and Nucleotides - Free-Radical-Induced DNA Damage and Its Repair - page 259

The allyl radical can react with another • CH 2 OH to form either the hydroxyethyl
derivative [reaction (199)] or its isomer with an exocyclic double bond [reactions
(200)].
The latter appears to be much more reactive towards • CH 2 OH than 1,3Me 2 Thy
itself, and reaches only such a low steady-state. Instead, its addition products
(compiled in Table 10.22) are found to increase linearly with dose [for the first
steps to these products see reactions (201)−(203)].
