Abstract
Influenza virus infection constitutes a significant health problem in need of more effective therapies. We have recently identified ((2R,3S,4R,5R)-3-acetoxy-5-(4-benzamido-2-oxopyrimidin-1(2H)-yl)-4-fluoro-3,4-dimethyl-tetrahydrofuran-2-yl) methyl benzoate (18c) as a potent influenza virus inhibitor. We now here report the synthesis and evaluation of a series of C-3' modified ribose nucleosides. These novel compounds were prepared, primarily by taking known ((2R,3R,4R)-3-benzoyloxy-4-fluoro-4-methyl-5-oxo-tetrahydrofuran-2-yl)methyl benzoate (1) and converting it in to C-3 keto sugar (7), reacting C-3 keto group with methyl magnesium bromide, followed by coupling these sugars with purine and pyrimidine bases. Anti influenza viral activity was determined by screening against both A and B viral strains.
