Synthesis and conversions of polyhedral compounds. 25. Synthesis and convepsions of certain oxindole derivatives of 1,3-diazaadamantane and 3,7-diazabicyclo[3.3.1]nonane

Abstract

By the reaction of 1,5-dimethyl-9-oxo-3,7-diazabicyclo[3.3.1]nonane with isatin and a number of its derivatives, spiro(1,3-diazaadamantane-2,3′-oxindoles) have been synthesized. In the case of 5-bromoisatin, either 3-(3-hydroxyoxindolyl)-3,7-diazabicyclo[3.3.1]nonane or the corresponding spirane is obtained, depending on the temperature. The interaction of these products with acetic anhydride has been studied.
