3,7-Diaminobicyclo[3.3.1]nonanes were synthesized starting from adamantane-2-on. endo,endo-3,7-Diaminobicyclo[3.3.1]nonane was obtained through Schmidt rearrangement of 3,7-bicyclo[3.3.1]nonane dicarboxylic acid. The endo,exo-isomer was synthesized by Schmidt rearrangement of 3-oximinobicyclo[3.3.1]nonane-7-carboxylic acid in acidic media following reduction of oximino group which was unprecedentedly

Abstract A facile and convenient synthesis of ethyl 5-oxohomoadamantane-4-carboxylate is reported, and its chemical properties as a cage analogue of acetoacetic ester are investigated. Various derivatives of homoadamantane were synthesized through the reaction of 5-oxohomoadamantane-4-carboxylate with electrophilic agents, binucleophiles, and hydrazoic acid. Some new unusual products were obtained

transformations. Reductive amination of substituted homoadamantane-5-ones gave several homoadamantane-fused nitrogen heterocycles, which could be considered as GABA- and/or ∂-aminovaleric acid analogues. Reduction products of several substituted ketones were observed as single products when treated with organomagnesiumreagents. These deviations from the general chemical reactivity patterns are associated with
