Reactions of 2-amino-aryl alcohols with beta-ketoesters catalyzed by a catalytic amout of FeCl3 via tandem benzylation-cyclization produce the corresponding 3-quinolinecarboxylic esters in good to high yields. Extending this methodology to propargylation-cyclization, 2-nitrophenyl proparoyl alcohols with beta-ketoesters catalyzed by FeCl3 and SnCl, also produce the 4-alkyne-3-quitiolinecarboxylic esters. The mechanistic details of this benzylation/proparoylation and cyclization cascade process are also discussed.

towards construction of amide C–N bonds under mild conditions through rhodium(III) catalysis has been explored. Previous waste-free amidations were generally limited to the condensation of carboxylic acids and amines. In this report, we directly applied amination of the aldehyde C(sp2)–H bond to extend the scope of amidation reactions. The amination shows a wide substratesscope, and several important
