Heteroatom-substituted C(sp3)-rich polycyclic hydrocarbon rings, isosteric to heterocyclic rings, are not common due to the challenging synthesis. Now a photoredox-catalysed strategy to insert amidyl radicals into bicyclo[1.1.0]butanes is presented, providing direct access to 2-oxa-4-azabicyclo[3.1.1]hept-3-enes.
