title: Anti-influenza A activity of some N-substituted bicyclo[3.2.1]octane-3-spiro-3'-pyrrolidine hydrochlorides: synthesis and structure.
abstract: Some N-substituted bicyclo[3.2.1]octane-3-spiro-3'-pyrrolidine hydrochlorides (IX-XII) prepared from bicyclo[3.2.1]octan-3-one (I), were assayed in vitro against influenza A viruses. All materials showed activity similar to 1-adamantanamine hydrochloride. A 1H-NMR study revealed only one isomer at the spiro carbon atom.
