addition of 2-alkylazaarenes to α-keto amides to furnish azaarene incorporated α-hydroxy amides has been developed with a wide range of substrates in moderate to excellent yields, respectively. Chemoselective alkylation of the keto functionality of the α-keto amides in the presence of simple ketones is the key advantage of this Zn-catalyzed transformation. This approach has been demonstrated to one gram-scale
