Methods have been developed for the synthesis of 2,3'-biquinolines, their 1',4'-dihydro derivatives, 3-pyrid-2-ylquinolines, and 3-pyrazin-2-ylquinoline based on the interaction of hetarylethylenes and vinyl butyl ether with imidoyl chlorides and Vilsmeier complexes. Using the example of the synthesis of 3-hetarylquinolines and their dihydro derivatives the synthetic possibilities of the Vilsmeier method were shown for creating various bonds in different quinoline nuclei of the bisheterocyclic system.

During a structure–activity relationship optimization campaign to develop an inhibitor of AraC family transcriptional activators, we discovered an unexpected transformation of a previously reported inhibitor that occurs under the assay conditions. Once placed in the assay media, the 3,4-disubstituted dihydroquinoline core of the active analogue rapidly undergoes a decomposition reaction to a quaternary 3-substituted biquinolinium. Further examination established an SAR for this chemotype while also demonstrating its resilience to irreversible binding of biologically relevant nucleophiles.
