The synthesis of several 2,2-dialkyladamantyl-1-amines through the combination of a Ritter reaction with a Wagner-Meerwein rearrangement from noradamantane alcohols is reported. Several of the novel amines displayed low micromolar activities against several H1N1 influenza virus strains, including the amantadine-resistant A/PuertoRico/8/34 strain. Most of the compounds did not show cytotoxicity for MDCK cells.
