This study explores the synthesis and characterization of a series of 1,9-diazahomoadamantane-4,6-dione derivatives, compounds with extremely interesting pharmacological properties. Several new derivatives were prepared through reactions involving condensation and hydrazine treatment to obtain Schiff bases and hydrazone derivatives, respectively. The identity of the molecules in the samples was determined based on data from the infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy. The synthesis of [(4E,6E)-4,6-dihydrazineylidene-1,9-diazatricyclo[5.4.1.1³,⁹]tridecane] was done by the reaction of 1,9-diazahomoadamantane-4,6-dione with hydrazine hydrate, and Schiff bases were produced by condensation with substituted aromatic amines. The structures of the prepared materials were supported by their IR and NMR spectra which depicted their characteristics, such as carbonyl, imine, and hydrazine groups which are among the biological active groups. These findings pave the way for the creation of new molecules that could be pharmacologically active with possible applications in the development of new drug candidates based on the diazahomoadamantane scaffold.
