Visible-light mediated heterogeneous C–H functionalization of tertiaryamines provides access to a variety of α-amino amides. An oxidative, titanium dioxide catalyzed, Ugi-type, three-component reaction has been developed in which the catalyst can be recycled without loss of activity.

reaction for the synthesis of α-amino amides via C(sp3)–Hbondactivation. The active intermediate generated by the difunctionalization of isocyanide undergoes intermolecular rearrangement rather than the easier intramolecular rearrangement. This may be caused by a six-member ring transition state. In addition, under metal-free and external oxidant-free conditions, large-scale synthesis and good functional
