5′-Chloro-5′-deoxy-2′,3′-O-isopropylidene-6-fluoro nebularine

Abstract

In this paper, we report on the synthesis and spectroscopic characterization of the novel nucleoside 5′-chloro-5′-deoxy-2′,3′-O-isopropylidene-6-fluoro nebularine, obtained as a side product during the second step of the synthesis of 5′-fluoro-5′-deoxy-5-aminoimidazole-4-carboxamide-β-d-riboside (5′-F-AICAR), a non-phosphorylable analogue of 5-aminoimidazole-4-carboxamide-β-d-riboside (AICAR).
