Regioselective One-Step Synthesis of 4-Fluoroalkylated Isoquinolines via Carbopalladation Reaction of Fluorine-Containing Alkynes
The palladium-catalyzed annulation reaction of fluoroalkylated alkynes with various 2-iodobenzylidenamines was investigated. In the presence of a catalytic amount of Pd(PPh3)4, the reaction took place smoothly to give the corresponding 4-fluoroalkylated isoquinoline in high yield as a single isomer....

Abstract | The palladium-catalyzed annulation reaction of fluoroalkylated alkynes with various 2-iodobenzylidenamines was investigated. In the presence of a catalytic amount of Pd(PPh3)4, the reaction took place smoothly to give the corresponding 4-fluoroalkylated isoquinoline in high yield as a single isomer. No other regioisomer was detected. |
