Three-component reactions with ortho-alkynylbenzaldehydes, primary amines, and pronucleophiles (Nu-H), such as CHCl3, proceeded to give 1,2-dihydroisoquinoline derivatives in good to high yields in the absence of any catalysts under mild reaction conditions.
Three-Component Reaction of Arynes, Quinolines, and Chloroform: Two-Step Synthesis of 2-Quinolinones from Quinolines
Reaction of quinoline with benzyne prepared from benzenediazonium-2-carboxylate and chloroform gave 1-phenyl-2-trichloromethyl-1,2-dihydroquinoline in 79% yield. Basic hydrolysis of dihydroquinoline by KOH resulted in the formation of 2-quinolinone in 85% yield.
