Preparation of nucleosides derived from 2-nitroimidazole and d -arabinose, d -ribose, and d -Galactose by the Vorbrueggen method and their conversion to potential precursors for tracers to image hypoxia

Schweifer, Anna,Hammerschmidt, Friedrich

experimental part, p. 8159 - 8167 (2012/01/03)

2-Nitroimidazole was silylated using hexaethyldisilazane and then reacted with 1-O-acetyl derivatives of d-arabinose, d-ribose, and d-galactose in acetonitrile at mild temperatures (-20 °C to rt), catalyzed by triethylsilyl triflate (Vorbrueggen condition
