Investigations in 2,3′-biquinoline series 24. Synthesis of 3-hetarylquinolines and their 1,4-dihydro derivatives under conditions of the Vilsmeier reaction
摘要:
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.

Various heterocycles have been introduced on the 3-picoline nucleus via a regioselective BuLi-Me2N(CH2)(2)OLi (BuLi-LiDMAE) mediated para-lithiation. Useful methyl-polyheterocycles were efficiently prepared by a one-pot lithiation-stannylation-Stille coupling sequence. (C) 2001 Published by Elsevier Science Ltd.
