A unique and efficient method for one-pot synthesis of diverse 4-quinolones from simple and readily available primary anilines and alkynes viaCu(I)-catalyzed direct cyclization has been developed. The (thio)phenols were also found to visible substrates for this reaction. Moreover, an unprecedented synthesis of dihydroepindolidiones has been demonstrated by using secondary anilines as the versatile

[GRAPHICS]Regiospecific carbonylative annulation of sigma-iodophenol acetates and acetylenes mediated by palladium-thiourea-dppp complex in the presence of base at 40 degrees C under a balloon pressure of CO generates diversified flavones in high yields. This newly developed synthetic technology provides a highly efficient method for potential application to the combinatorial synthesis of those heterocycles on the solid support.
