Regioselective Pd-catalyzed α-alkylation of furans using alkyl iodides.

Herein, direct alkylation of the C-H bond at the α-position of furans catalyzed by palladium catalyst is reported. This protocol targets α-alkylfurans, achieving moderate to good yields under very practical reaction conditions. With a broad scope of substrates and good functional group tolerance, this method will has promising utility in medicinal chemistry.
