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]:
提供了一种新颖的手性铱(III)配合物;以及一种使用该手性铱(III)配合物通过更经济、更简便的生产工艺从2-取代喹啉制备手性活性的2-取代-1,2,3,4-四氢喹啉的方法。所披露的制备手性活性的2-取代-1,2,3,4-四氢喹啉的方法包括在氢供体化合物和含有手性脯氨酰胺化合物配体的铱(III)配合物的存在下还原由式[I]表示的喹啉化合物,以得到由式[II]表示的手性活性的2-取代-1,2,3,4-四氢喹啉。
