Abstract

A Pd/C/Zn mixture with alcohols has been revealed to be an efficient transfer hydrogenation system to quinolines. Furthermore, the metals mixture is able to activate alcohols as N- alkylating agents in a hydrogen autotransfer process. 1, 2, 3, 4-Tetrahydroquinolines and N- alkylated tetrahydroquinolines from quinolines have been obtained with excellent yields in one step.
