A series of substituted quinolines was prepared from arylamines, aldehydes, and terminal olefins (see scheme). The palladium‐catalyzed sequentialformation of CCbonds proceeds smoothly with both electron‐deficient and electron‐rich olefins. When acrylic acid is used as terminal olefin, decarboxylation occurs to provide 2‐substituted quinolines.

report the divergent synthesis of quinolines and quinolones via a transferhydrogenativecondensation of ortho-nitrobenzyl alcohols in one step. The reaction proceeded using the cyclopentadienone iron complex without any additional redox reagents. After transferhydrogenation between ortho-nitrobenzyl alcohols and secondary alcohols, the subsequent Friedländer annulation affords polysubstituted quinoline
