The double Mannich condensation of 2-quinolizidone with formaldehyde and methyl amine resulted in the 11-methyl-7,11- diazatricyclo[,7]tridecan-13-one of endo-type selectively. The stereochemistry, isomerism and conformational behaviour of derivatives obtained by reduction at C-13 were investigated extensively by one- and two- dimensional 1H, 13C and 15N NMR spectroscopy. The site of the protonation and its effect on the conformational equilibria and chemical shifts were also revealed.
