          Abstract

          Tramadol is a drug with analgesic properties. This compound and five of its analogous were synthesized: N-demethyl (M2), O-demethyl (M1), O-ethyl-O-demethyl, O-benzyl-O-demethyl and N-benzyl-N-demethyl. All compounds were prepared as their hydrochlorides and as racemic mixtures. The synthesis started with the aminoketones; 2-(N-benzyl, N-methyl)aminomethyl cyclohexa-none and 2-dimethylaminomethyl cyclohexanone, prepared by means of a Mannich reaction of cyclohexanone, paraformaldehyde and the corresponding amino hydrochloride. The aminoketones were coupled with the organolithium compounds derived from the corresponding 3-bromoalkoxybenzenes.

Las aminocetonas así obtenidas, fueron acopladas con los derivados organolitiados provenientes de la reacción de n-butillitio con los 3-bromoalcoxibencenos correspondientes.
