The synthesis of quinolines has been achieved through a one‐pot, two‐step tandem reaction catalyzed with AgPd alloy nanoparticles supported on carbon. AgPd alloy nanoparticles catalyzed the coupling of a ketone with a primary alcohol through a hydrogen autotransfer process, which yields α‐alkylated ketones under an Ar flow. These are reacted with 2‐aminobenzyl alcohols in a modified Friedländer synthesis
the synthesis of functionalized quinolines from 2-aminobenzyl alcohols with α,β-unsaturated ketones. This method exhibits tolerance to various functional groups and high efficiency, is environmentally benign, and can be performed on a gram scale. Control experiments suggest that this transformation is accomplished by iridium complex catalyzed transferhydrogenation, which is then followed by Friedländer
