Abstract
CMR spectra of the following bicyclo[2,2,2]octane compounds were measured: 1‐azabicyclo[2,2,2]octan‐3‐one (3), 2‐azabicyclo[2,2,2]octan‐3‐one (5), bicyclo[2,2,2]octaone (4), 3‐ethyl‐1‐azabicyclo[2,2,2]oct‐2‐ene (6) and of the Z and E isomers of 3‐ethylidene‐1‐azabicyclo‐[2,2,2]octane (1 and 2). The attribution of the signals and confirmation of the Z and E configuration of isomers (1) and (2) is described.Keywords
