Cilobamine is a drug which acts as a norepinephrine-dopamine reuptake inhibitor (NDRI) and has stimulant and antidepressant effects.{{cite journal | vauthors = Leeson GA, Shaath ZA, Biedenbach SA, Yarrington JT, Okerholm RA | title = Dose related induction of the drug metabolizing enzymes of rat liver by cilobamine | journal = Fundamental and Applied Toxicology | volume = 4 | issue = 2 Pt 1 | pages = 261–9 | date = April 1984 | pmid = 6724198 | doi = 10.1016/0272-0590(84)90127-1 }}{{Cite journal | vauthors = Wager S, Quitkin F, Stewart J, McGrath P, Harrison W, Markowitz J, Tricamo E | title = Cilobamine in the treatment of atypical depression | journal = Human Psychopharmacology: Clinical and Experimental | year = 1988 | pages = 201–205| volume = 3 | issue = 3 | doi = 10.1002/hup.470030308 | s2cid = 145253439 }}
It can clearly be seen that the structure is based on dichloroisoprenaline that has been fused onto the bicycloalkane scaffold.
Synthesis
An intramolecular Dieckmann cyclization on methyl 4-(2-methoxy-2-oxoethyl)cyclohexanecarboxylate [1401222-79-4] (3) with sodium hydride base gives reaction Methyl 3-oxobicyclo[2.2.2]octane-2-carboxylate [30144-30-0] (4). Treatment with sodium nitrite introduces an isonitroso group adjacent to the ketone, giving 3-Hydroxyiminobicyclo[2.2.2]octan-2-one, [https://pubchem.ncbi.nlm.nih.gov/compound/131066320 CID:131066320] (5). Addition of the aryl Grignard reagent, and reduction of the oxime gives [https://pubchem.ncbi.nlm.nih.gov/compound/154108204 CID:154108204] (6). A reductive amination of the primary amino group with acetone then completed the synthesis of cilobamine (7).
