etheno- (syn-chloro- series) or benzo- (anti-chloro- series) π-electrons. The high barriers to inversion at nitrogen together with some control over the ratio of invertomers allow observation of a different reaction pathway for each invertomer when reactions are performed at low temperatures; approaches which allow selection of the benzo- participation route (giving 6,7-benzo-derivatives of the 1-azabicyclo[3
