3-(2-Hydroxy-2-phenylethyl)- and 3-(2-hydroxy-1-phenylethyl)adenine, DNA adducts derived from styrene, along with their 9-substituted analogues were prepared by alkylation of 8-bromoadenine with corresponding allyl-protected bromohydrins followed by a new deallylation procedure using tetrakis(triphenylphosphine)palladium catalyzed reductive cleavage by poly(methylhydrosiloxane) in the presence of p-toluenesulphonic
3-(2-羟基-2-苯基乙基)-和3-(2-羟基-1-苯基乙基)腺嘌呤,苯乙烯衍生的DNA加合物及其9-取代的类似物是通过将8-溴腺嘌呤与相应的烯丙基烷基化而制备的-保护的溴代醇,然后采用新的脱羧方法,使用四(三苯基膦)钯在对甲苯磺酸的存在下,通过聚(甲基氢硅氧烷)催化还原裂解。事实证明,该新方法对于嘌呤衍生物是有用的,嘌呤衍生物对其他脱羧方法具有抗性。使用2D NMR实验HMBC和HMQC指定位置异构体的结构。
