Quinolines have been obtained through the indirect Friendländer annulation starting from 2-aminobenzyl alcohol or derivatives from it and ketones catalyzed by N-heterocyclic carbene, and the synthesis of polysubstituted quinolines through a one-pot, two-step tandem reaction starting from readily available ketones and alcohols via alpha-alkylation and indirectFriedländer annulation under air also has

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
