Proximity Effects: the Observation by 1H NMR of Steric Compression of the Methano Bridge Protons of Polycyclic Norbornanes Possessing Adjacent Carbon, Oxygen and Nitrogen Bridges
Proximity effects of neighbouring heteroatom bridges (oxygen, nitrogen) cause steric compression shifts in the 1H NMR chemical shifts of the bridge methano protons in fused norbornanes. This observation provides a simple 1D NMR method for elucidating the stereochemical outcome of cycloaddition reactions that produce fused norbornane structures.
