Polycyclic aminocyclopropanes

On the other hand the amino moiety in some bi- or polycyclic aminocyclopropanes could be substituted by diazotation without appreciable ring-opening 56.61,110.124,147,152 great steric influence of the diazonium group on the...

The acid-catalysed rearrangement of N-aryl 2-azabicyclo [3.1.0]hexanes, where the aromatic system is conjugated with an alkene group located at the ortho position relative to the nitrogen atom, gives dihydroquinolines or polycyclic aminocyclobutanes via an iminium intermediate formed by protonation of the aminocyclopropane moiety...
