Abstract

1,5-Dimethylbispidinone (1,5-dimethyl-3,7-diazabicyclo[3.3.1]nonan-9-one) reacts with natural ketones, including optically active ones, to give new aminal-type compounds combining diazaadamantane and aliphatic fragments. [ABSTRACT FROM AUTHOR]

Abstract

The possibility of the complex formation of three bispidines with copper(ii) chloride and acetate in a deuterated DMF solution was studied by NMR titration. For all ligands, the formation of complexes with copper(ii) chloride was clearly detected based on the changes in the signals in the proton NMR spectra. The formation of complexes with copper(ii) acetate was not observed for any of the ligands. The results of the study can be used in the design of metal complex catalysts for the Henry reaction.
