A general procedure was proposed for synthesizing 3-R-1-adamantyl methyl ketones from the corresponding adamantanecarbonyl chlorides and dimethyl malonate in toluene (benzene) in the presence of sodium hydroxide. Intermediate dimethyl (3-R-1-adamantylcarbonyl)malonates can also be isolated. The resulting ketones were brought into reactions with hydroxylamine and formamide in the presence of formic acid to obtain the corresponding oximes and 1-(3-R-1-adamantyl)ethylamines. Dimethyl (3-R-1-adamantylcarbonyl)malonates reacted with phenylhydrazine to give adamantyl-substituted 4,5-dihydropyrazol-5-one derivatives.

The hydroxy metabolites of rimantadine (3-5) were synthesized and compared to amantadine (1) and rimantadine (2) for their ability to inhibit the replication of influenza viruses in vitro. All three metabolites were inhibitory to wild-type influenza A viruses (H3N2 and H1N1). In particular, 2-hydroxyrimantadine (3) showed similar activity to amantadine, but the 3- and 4-hydroxy metabolites (4 and 5, respectively), both of which are found in rimantadine-treated patients, showed only modest inhibitory activity. A rimantadine-resistant isolate of influenza A virus exhibited cross-resistance to amantadine and to each of the metabolites 3-5. None of the compounds were effective against influenza B virus.

Along Iffland's reactions from 1-adamantyl methyl ketone, (1-adamantyl)acetone, 3-hydroxy-1-adamantyl methyl ketone and N-bromosuccinimide were obtained the corresponding bromonitro derivatives that on reduction with sodium borohydride afforded 1-(1-adamantyl)-1-nitroethane, 1-(1-adamantyl)-2nitropropane, and 1-(3-hydroxy-1-adamantyl)-1-nitroethane.
