First cross-coupling reactions of arylmagnesates: a convenient access to heteroarylquinolines
摘要:
2-, 3- and 4-Bromoquinolines were converted to the corresponding lithium tri(quinolyl)magnesates at -10degreesC on treatment with Bu3MgLi in THF. The resulting organomagnesium derivatives were involved in catalyzed cross-coupling reactions with heteroaryl bromides and chlorides to afford functionalized quinolines.

A condensed-cyclic compound is represented by Formula 1. An organic light-emitting device includes a first electrode, a second electrode facing the first electrode, and an organic layer between the first electrode and the second electrode and including an emission layer, where the organic layer includes at least one of the condensed-cyclic compounds represented by Formula 1.
2-, 3- and 4-Bromoquinolines, were converted to the corresponding lithium tri(quinolinyl)magnesates at -10degreesC when exposed to Bu3MgLi in THF. The resulting organomagnesium derivatives were quenched with various electrophiles or involved in metal-catalyzed coupling reactions with heteroaryl halides to afford functionalized quinolines.

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.
