Condensation and cyclization of ethyl 2-piperidineacetate with cyclohexanone gave a vinylogous lactam, 1, 2, 3, 4, 4a, 5, 7, 8, 9, 10-decahydro-6H-benzo [c] quinolizin-6-one (VII). The same reaction with 2-tetralone gave four compounds, all having the vinylogous lactam grouping. The structures of these compounds were assigned by their infrared, ultraviolet and nuclear magnetic resonance spectra.
