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

Sodiumborohydride reduces the imide carbonyl groups of 5,5‐diallyl‐1‐methyl‐barbituric acid (1) at position 4 to a methylene group and at position 6 to a primary hydroxy group which has been verified by analysis of the high resolution 1H‐NMR and mass spectra of the product 3.
