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
