The reaction of 2'-deoxyguanosine with the alpha,beta-unsaturated aldehydes trans-2-octenal, trans-2-nonenal, trans-2-decenal, trans,trans-2,4-nonadienal, and trans,trans-2,4-decadienal in THF gives rise to three novel adducts: 3-(2'-deoxy-beta-D-erythro-pentafuranosyl)-7-[3-hydroxy-1-(3-(2'-deoxy-beta-D-erythro-pentafuranosyl)-3,5-dihydro-imidazo[1,2-a]purin-9-one-7-yl)-propyl]-3,5-dihydro-imidazo[1,2-a]purin-9-one (A7) and 3-(2'-deoxy-beta-D-erythro-pentafuranosyl)-7-(tetrahydrofuran-2-yl)-3,5-dihydro-imidazo[1,2-a]purin-9-one (A8 and A9), which are not observed in the absence of THF. These adducts
