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.
Establishing the correlation between catalytic performance and N→Sb donor–acceptor interaction: systematic assessment of azastibocine halide derivatives as water tolerant Lewis acids
A series of organoantimony(III) halidecomplexes with a tetrahydrodibenzo[c,f][1,5]azastibocine framework were synthesized and employed as water tolerant Lewis acid catalysts. The results of a systematic structure–activity relationship study demonstrated that the strength of N→Sb donor–acceptor interaction could be synergistically modulated by tuning the properties of the nitrogen substituents and

A simple and efficient method has been developed for the synthesis of quinoline derivatives from N-alkyl anilines and alkynes or alkenes by iron-catalyzed oxidative couplingreactions. A variety of substituted quinolines are prepared in good to excellent yields.

Gold-catalyzed synthesis of quinoline derivatives via [4 + 2] annulation between terminal arylynes and nitrones is described. Our mechanistic analysis supports the participation of alkynylgold intermediates, instead of a typical gold–carbene species in recently reported gold catalysis. These nucleophilic alkynylgold species react with nitrones via Povarov-type reactions. Cheap, readily available materials
