Truncated phosphonated C-1′-branched N,O-nucleosides have been synthesized in good yields by 1,3-dipolar cycloaddition methodology, starting from N-methyl-C-(diethoxyphosphoryl)nitrone 7. Preliminary biological assays show that β-anomers are able to inhibit HIV in vitro infection at concentrations in the micromolar range. Higher SI values with respect to AZT indicated that the compounds were endowed

膦酸化的C-1'-支链N,O-核苷都在良好的产率通过1,3-偶极环加成的方法被合成,从开始Ñ甲基Ç - (二乙氧基

生物学分析表明,β-端基异构体能够以微摩尔范围的浓度抑制HIV体外感染。相对于AZT,较高的SI值表明该化合物具有低细胞毒性。
