A one-pot I2-mediated annulation reaction of substrates containing diamino groups and aldehydes has been developed viaoxidativeC–Nbondformation. This general and environmentally benign synthetic approach provides facile access to a variety of 1,3-diazaheterocyclic compounds, including quinazolinones, benzimidazoles, and cyclic amidines.

Aminal radicals were generated by reduction of the corresponding amidine or amidinium ion. The intermediate radicals participate in C–C bond-forming reactions to produce fully substituted aminal stereocenters. No toxic additives or reagents are required. More than 30 substrate combinations are reported, and chemical yields are as high as 99%.

Racemates are obtained from one of the enantiomers, or an enantiomerically enriched mixture, of an optically active quinazolinone derivative by reaction of the compound with an alkali alkoxide of a primary alcohol and isolation of the racemate.
