Synthesis of 2-fluoronoraristeromycin and its inhibitory activity against Plasmodium falciparum S-adenosyl-L-homocysteine hydrolase.

Palladium-coupling reaction of (1S, 4R)-cis-4-acetoxy-2-cyclopenten-1-ol with sodium salt of 2-fluoroadenine resulted in the formation of (1S,4R)-4-(6-amino-2-fluoro-9H-purin-9-yl)cyclopent-2-en-1-ol. Subsequent oxidation was carried out with osmium tetraoxide (OsO(4)) in the presence of 4-methylmorpholine N-oxide (NMO) to give 2-fluoronoraristeromycin, possessing significant inhibitory activity against recombinant Plasmodium falciparum SAH hydrolase.
