Abstract

Carbon‐13 NMR spectra of various 8‐aryl‐8‐azabicyclo[3.2.1]oct‐3‐en‐2‐ones and other related compounds, including tropinone, were determined, and the predominant conformation at the bridgehead nitrogen was established. The full assignment of resonances from proton decoupled and coupled spectra was based on the analysis of the splitting pattern and characteristic chemical shifts. The use of the determined ^13^C NMR spectra in the assignment of ^13^C NMR data in related but more complicated structures is also proposed.
