Electrocatalytic Reduction of Quinolines and Ketones by Using Lewis Base-Ligated Borane as a Hydrogen Donor
By employing Lewis base-ligated boranes(LB-BH3)as the hydrogen donor,a general and straightforward electrochemical protocol for transfer hydrogenation of quinoline was developed to access a variety of bioactive 1,2,3,4-tetrahydroquinolines.Moreover,this developed protocol was successfully applied to the reduction of other double bonds,including C=O,N=N and C=C bonds.This method has some characteristics such as simple operation,mild reaction conditions and a wide range of substrates.
