Abstract
An efficient [2 + 1 + 3] cyclization reaction of aryl methyl ketones, arylamines, and 1,3-dicarbonyl compounds provides 2-aryl-4-quinolinecarboxylates in good yields under mild conditions. This metal-free process achieved a C-C bond cleavage of 1,3-dicarbonyl compounds for use as a C1 synthon.
