Palladium-catalyzed iminoannulation

The palladium catalyzed iminoannulation and carboxyannulation of alkynes and an appropriate aryl/vinyl halide is an efficient tool to construct six membered nitrogen and oxygen heterocycles. The process encompasses the concomitant formation of a carbon-carbon and a carbon-heteroatom bond. [Pg.80]

A series of substituted /0-carbolines 44 and y-carbolines 45 were synthesized by the palladium-catalyzed iminoannulation of internal alkynes 46 with the tert-butylimines generated from TV-substituted 3-iodoindoIe-2-carboxaldehydes 47 and 2-haloindole-3-carboxaldehydes 48, respectively. The chemistry is effective for a wide range of alkynes, including aryl-, alkyl-. [Pg.150]

Larock s group developed a procedure for the preparation of pyridines via palladium-catalyzed iminoannulation of internal acetylenes [119]. A wide variety of aryl acetylenes undergo this process in... [Pg.72]
