spectrometry and nuclearmagneticresonance spectroscopy. The adducts were prepared by reacting purine nucleobases or nucleosides with epoxybutene (EB) or diepoxybutane (DEB) followed by HPLC separation. The reaction of guanine (Gua) with EB resulted in two isomeric products, N7-(2-hydroxy-3-buten-1-yl)guanine (EB-Gua I) and N7-(1-hydroxy-3-buten-2-yl)guanine (EB-Gua II). The reaction of adenine at N3
