title: Synthesis of certain 2-aminoadamantane derivatives as potential antimicrobial agents.
abstract: 1-(2-Adamantyl-3-(5-arylhydrazono-6-methyl-4-oxopyrimidin -2-yl)guanidines, 2-(2-adamantylamino)-4-amino-s-triazine and its 6-chloromethyl derivative were prepared by cyclization of 1-(2-adamantyl)biguanide.HCl with ethyl 2-arylhydrazono-3-oxobutyrates, ethyl formate and ethyl chloroacetate, respectively. 1-(2-damantyl)-3-(4,5-dioxo-2-imidazolidinylidene)guanidine was used as intermediate for the synthesis of amides, hydrazide and azomethine derivatives of alkyl 2-(2-adamantylamino)-4-amino-s-triazine-6-carboxylates. The antimicrobial testing of the prepared compounds proved that an azomethine derivative was the most active. It showed a marked bacteriostatic effect against Staphylococcus aureus and Bacillus subtilis.
