Abstract:1-alpha- and 1-beta-D-Arabinofuranosyl-2-nitroimidazole (alpha-AZA and beta-AZ A) are synthons for a number of potential markers of tissue hypoxia. A one pot synthesis in which 2-nitroimidazole is coupled with a mixture of alpha- and beta-1-O-acetyl-2,3,5-tri-O-benzoyl-D-arabinofuranose in the presence of stannic chloride, followed by deprotection using ammonia/methanol, is described Previously reported conditions for coupling 2-nitroimidazole to 1-alpha-bromoarabinofuranose protected by base-hydrolyzable grou… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
