a N2O-saturated solutions of 2 (1.0 mM) at natural pH irradiated for 800 Gy (46.7 Gy/min); b Based on LC–MS and high-resolution MS/MS analysis; c cf. Scheme 5; d Generated from the reactions of H• atoms, see Scheme 4; e Based on the intensity peaks of LC. f Number of diastereoisomers; g tentative assignment due to low intensity, alternatives αC(2)—αS(1) or αS(1)—αS(1).
