Efficient route to 4-substituted-2(5H)-furanones, 2(1H)-quinolones, and pyrones by nickel-catalyzed cross-coupling of arenesulfonates with organozinc reagents
Nickel (II)-catalyzed cross-coupling reactions of 4-tosyl-2(1H)-quinolone, pyrone, and 2(5H)-furanone with various organozinc reagents provide an efficient and practical method for the high-yielding synthesis of 4-substituted 2(1H)-quinolones, pyrones, and 2(5H)-furanones.
