A novel protocol for the synthesis of highly functionalized benzo[ b ][1,5]diazocin-6(5 H )-one derivatives (BDCOs, 4 and 5 ) from 2-aryl-1 H -indoles and 1,1-enediamines was developed via a complex cascade of reactions including regioselective free radical oxidation, the 1,2-addition of imine, imin...
