supporting information, p. 3083 - 3086 (2017/06/23)
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 effective CuI-trans-N,N′-dimethylcyclohexane-1,2-diamine (DMCDA)-K2CO3-catalyzed coupling reaction of 2-pyridones with aryl halides is described. Under our conditions, DMCDA was found to be an effective catalyst that facilitates the coupling reactions even in toluene, a common industrial solvent. In addition, 3-bromopyridine could also be coupled effectively under these conditions, indicating that the catalytic reactivity of this system is high. The reaction could be applied for polymer modification and iterative oligo-pyridone synthesis.
