Radical heterocyclizations triggered by electron transfer to amide‐type carbonyls, using SmI2‐H2O, provide straightforward access to bicyclic heterocyclic scaffolds containing bridgehead nitrogen centers. Furthermore, the first radical heterocyclization cascade triggered by reduction of amide‐type carbonyls delivers novel, complex tetracyclic architectures containing five contiguous stereocenters with

Amidines bearing simple alkenes undergo aminal radicalcyclisation upon treatment with SmI2. The mild, reductive electron transfer process delivers medicinally-relevant, polycyclic quinazolinone derivatives in good to excellent yield and typically with complete diastereocontrol.
