9-(1-Fluoro-5-hydroxypentan-2-yl)-9H-guanine: synthesis and evaluation of antiviral activity
摘要:
5-Fluoro-4-tosyloxypentyl pivalate has been synthesized in four steps from 2-(fluoromethyl)tetrahydrofuran. Condensation with 2-amino-6-chloropurine gave the N-9 derivative, which was converted via the 6-methoxy analogue into 9-(1-fluoro-5-hydroxypentan-2-yl)-9H-guanine. The latter was evaluated, and found inactive, in a large variety of antiviral assays.

A facile aliphatic nucleophilic fluorination with cesium fluoride in the presence of molybdenum oxide as a catalyst has been demonstrated. Reactivity of molybdenum oxide in nanocrystal form was found to be chemoselective in the presence of water. Furthermore, the reaction is highly specific with alkyl sulfonate substrates.
