hydroacylative union of aldehydes and o-alkynyl anilines leads to 2-aminophenyl enones, and onward to substituted quinolines. The mild reaction conditions employed in this chemistry result in a process that displays broad functional group tolerance, allowing the preparation of diversely substituted quinolines in high yields. Extension to the use of o-alkynyl nitro arenes as substrates leads to 2-nitrochalcones
