GSK3082 – a hepatitis C virus RNA polymerase inhibitor – and a series of analogues with structural diversity at the 5-position were prepared from a 2,2,4,5-tetrasubstituted pyrrolidine obtained with a well-defined stereochemistry from the 1,3-dipolar cycloaddition of the chiral imino ester derived from leucine tert-butyl ester and (R)-2,3-O-isopropylideneglyceraldehyde with methyl acrylate. The chiral
GSK3082 –丙型肝炎病毒RNA聚合酶抑制剂–和一系列在5位具有结构多样性的类似物,是由2,1,2,4,5-四取代的吡咯烷通过1,3,3的明确立体化学制得的衍生自亮氨酸叔丁酯和(R)-2,3- O-异亚丙基甘油醛的手性亚氨基酯与丙烯酸甲酯的偶极环加成。甘油醛提供的手性2,2-二甲基-1,3-二氧戊环部分可作为不同取代基和官能团的合成等价物,这些转化通常需要温和的反应条件和简单的后处理程序。体外研究了所得GSK3082类似物的抑制活性在亚基因组HCV RNA复制系统的基于细胞的检测中。一些类似物表现出良好的抑制活性,在纳摩尔浓度范围内的IC50值。
