A Rh(III)-catalyzed oxidative annulation of pyridin-2(1H)-ones with alkynes via double C-H activation to produce highly functionalized 4H-quinolizin-4-ones is disclosed. This reaction features easily available starting materials, simple manipulation, a relatively wide substrate scope, and good functional group tolerance. The application of this protocol is demonstrated by the synthesis of a known fluorescent quinolizino[3,4,5,6-ija]quinolinium salt.

An efficient method for the N-arylation of pyridin-2(1H)-ones and the related heteroaromatic lactams has been established via ligand-coupling reactions using tri- or tetra-aryl organobismuth(V) reagents such as triarylbismuth dichlorides. Also, N-alkenylation of pyridin-2(1H)-one was achieved similarly by using alkenyltriarylbismuth(V) reagents.
