5 ′-di-O-acetyl-5-formyl-2 ′-deoxy-β-L-uridine 1. Base hydrolysis of compounds 1 and 6 furnished their deacetylated analogues in good yields, whereas hydrolysis of 5 was troublesome. Structural features of these molecules are discussed by NMR spectra analyses and density functional theory quantum chemical calculations. The newly synthesized L-analogues show no significant activity against vaccinia and cowpox
作为正在进行的药物化学的一部分,我们在这里报告1-(2-脱氧-3,5-二-O-乙酰基戊呋喃糖基)-5-[(3-甲基-5-氧-1-苯基-4,5-二氢-4H-吡唑-4-亚甲基)嘧啶-2,4(1H,3H)-二酮5和5- [双(3-甲基-5-氧代-1-苯基-4,5衍生自3',5'的-二氢-4H-吡唑-4-基)甲基-1-(2-脱氧-3,5-二-O-乙酰基戊呋喃糖基)嘧啶-2,4(1H,3H)-二酮6 -二-O-乙酰基-5-甲酰基-2′-脱氧-β-L-尿苷1。化合物1和6的碱水解可提供高产率的脱乙酰基类似物,而5的水解很麻烦。通过NMR光谱分析和密度泛函理论量子化学计算讨论了这些分子的结构特征。新合成的L-类似物对牛痘和牛痘病毒没有显着活性。
