2-Aminobenzaldehydes as Versatile Substrates for Rhodium-Catalyzed Alkyne Hydroacylation: Application to Dihydroquinolone Synthesis

Amine for it! A cationic rhodium catalyst, which was assembled in situ from commercial components, promoted the reaction of a range of simple 2‐aminobenzaldehydes with terminal and internal alkynes in a series of intermolecular hydroacylation reactions. The products of this reaction, amino‐substituted enones, were efficiently converted into the corresponding dihydro‐4‐quinolones.
