Abstract
Provided are a novel chiral iridium(III) complex; and a method for producing optically active 2-substituted-1,2,3,4-tetrahydroquinolines from 2-substituted-quinolines with the use of the chiral iridium(III) complex through a more economical and easy production process. The disclosed method for producing optically active 2-substituted-1,2,3,4-tetrahydroquinolines comprises reducing a quinoline compound represented by formula [I]: in the presence of a hydrogen donor compound and an iridium (III) complex having a chiral prolinamide compound as a ligand to give an optically active 2-substituted-1,2,3,4-tetrahydroquinoline represented by formula [II]:
