Palladium-Catalyzed Synthesis of 3-Alkylphthalides via Carbonylative Cyclization ofo-Bromobenzaldehyde with 1,3-Dicarbonyl Compounds
摘要:
o-Bromobenzaldehyde reacts with 1,3-dicarbonyl compounds under carbon monoxide in the presence of a catalytic amount of PdCl2(PPh3)(2) to give the corresponding 3-alkylphthalides in moderate to good yields.
