Acrolein, a known mutagen, undergoes reaction in vitro under physiological conditions with both 2'-deoxyguanosine and native DNA to give rise to exocyclic adducts of the 5,6,7,8-tetrahydropyrimido[1,2-a]purine-10(3H)-one class having a hydroxyl group at either the 6 or the 8 position (these positions are respectively designated alpha and gamma when referring to the 1,N(2)-(propano-bridge).

丙烯醛是一种已知的诱变剂,在生理条件下与2'-脱氧鸟苷和天然DNA进行体外反应,生成5,6,7,8-四氢嘧啶[1,2-a]嘌呤-10( 3H)一类,在6或8位具有羟基(在提及1,N(2)-(丙烷桥)时,这些位置分别称为α和γ)。 8-羟基衍生物的诱变性很低,可能是因为在双链DNA中,该残基以开链醛形式[N(2)-(3-氧丙基)-2'-脱氧鸟苷]存在(5)。我们在这一领域的研究中,我们需要大量的6-羟基异构体。本论文描述了高产率的简单方法,用于批量合成6-羟基和6-甲氧基外环加合物1和3,以及一种新的有效合成1,N(2)()-(prop-1,3 -diyl)-2'-deoxyguanosine(4),以前用作研究1,N(2)环外加成dG的物理生物学影响的化学稳定模型。
