title: Synthesis and antiviral evaluation of unnatural beta-L-enantiomers of 3'-fluoro- and 3'-azido-2',3'-dideoxyguanosine derivatives.
abstract: 3'-fluoro-2',3'-dideoxy- (3) and 3'-azido-2',3'-dideoxy- (4) beta-L-ribofuranonucleoside derivatives of guanine have been synthesized and their antiviral properties examined. All these derivatives were regioselectively and stereospecifically prepared by glycosylation of 2-N-acetyl-6-O-(diphenylcarbamoyl)guanine 5 with a suitable peracylated L-xylo-furanose sugar 6, followed by appropriate chemical modifications. The prepared compounds were tested for their activity against HIV and HBV viruses, but they did not show significant activity.
